  1. Report to the CollaborationIndia-CMS Collaboration MeetingDelhi Univ, 27-28 March 2009 A. Gurtu Tata Institute of Fundamental Research, Mumbai

  2. LHC Schedule • All the damaged magnets replaced • In order to prevent any further similar incident precautionary hardware being installed at all magnets • This is a big job, in particular many thousand control cards have to be fabricated, prototypes will be available in May • Discussed in Chamonix meeting in February. Recommendations made to CERN council • CERN council: First collisions in October 09, followed by extended run at 8-10 TeV, till 200 – 300 pb-1 per experiment is collected (~ 1 year). AG: Report to the Collaboration, India-CMS meeting, Delhi Univ, 27-28 March 2009

  3. LHC schedule … • Note that above scenario is still a compromise between safety and need for quick physics • Only half the machine will be FULLY protected during the first run starting October 2009 • Remaining half will be done during the long shutdown starting in end-2010 • This schedule also has implications for experiments: NO SHUTDOWN in end-2009. So, all hardware will remain as it is, no repair, no additional installation possible. • Consequences for HO (Si-PM), RPC AG: Report to the Collaboration, India-CMS meeting, Delhi Univ, 27-28 March 2009

  4. Beam Conditions for Physics AG: Report to the Collaboration, India-CMS meeting, Delhi Univ, 27-28 March 2009 • Conclusion 5 TeV/beam for Physics • Machine Protection will be Tested with beam (at 0.5TeV energy levels) • 4 TeV “on the way” to 5TeV (limited in 2010) • Estimated integrated luminosity • during first 100 days of operation.. ≈100pb-1 • Peak L of 5.1031η (overall) = 10% gives 0.5pb-1/day • Peak L of 2.1032η (overall) = 10% gives 2.0pb-1/day • During next 100 days of operation.. ≈ 200pb-1? • Then towards end of year ions (to be planned in detail soon)

  5. Schedule with running in winter months Gains 20 weeks of LHC physics (independent of “slip”) AG: Report to the Collaboration, India-CMS meeting, Delhi Univ, 27-28 March 2009

  6. Statement on LHC Safety (1) AG: Report to the Collaboration, India-CMS meeting, Delhi Univ, 27-28 March 2009 Following the incident on 19 September the most crucial improvement foreseen was a more precise system to monitor (and protect) anomalously high resistance in a joint (splice) near the magnets. The development of this new enhanced ohmic resistance measurement is well under way and the new system will be installed and tested before beam operation. This will allow effective protection against thermal runaway in the magnet and interconnect splices. There is still no way to protect against an “instantaneous” rupture of a bus bar splice. It has been shown by simulations that the new system with a threshold trigger of 0.3mV (compared with the 1V of the system in place on 19 September) will protect the joints form thermal runaway “in all imaginable conditions”. Note if this system had been in operation the September incident would not have taken place. In the Risk analysis, we have mitigated against the re-occurrence of a thermal runaway of a splice. The risk-score is the product of the probability of the event and the level of the resulting impact.

  7. Statement on LHC Safety (2) AG: Report to the Collaboration, India-CMS meeting, Delhi Univ, 27-28 March 2009 • For the September 19 incident, the high impact was caused by collateral damage by: • High pressure build up damaged the magnet interconnects and the super-insulation • Perforation of the beam tubes resulted in pollution of the vacuum system with soot from the vaporization and with debris from the super insulation. • Until now and even after discussions in Chamonix there have not emerged any new ideas which would significantly reduce the pollution of the vacuum system in the event of a similar incident. • However, measures will be taken to vent the Helium more rapidly and therefore reduce the pressure increase and consequently minimize (eliminate?) the damage done to interconnects and super-insulation. • The already existing flanges in the Short straight sections (SSS) will be fitted with additional relief valves. Calculations have shown that this gives a factor of more than 9 with respect to the system existing on 19 September. These calculations show that the collateral damage (to the interconnects and super-insulation) which would be produced in a repeat incident of 19 September would be minor (significantly reduced). Such a repeat incident would not have a major impact on the spares situation for magnets . Whereas the collateral damage due to vacuum pollution would remain very similar to the September 19 incident.

  8. Strawman Luminosity Profile http://lhc-commissioning.web.cern.ch/lhc-commissioning/luminosity/09-10-lumi-estimate.htm • *Switching to 50 ns bunch spacing could be attempted at this stage. With 5.1010 protons/bunch the integrated L could be as high as 110 pb-1/month. • Implies impeccable performance of the machine. We (CMS) need to consider the impact of the long length of this run (and prepare appropriate plans). AG: Report to the Collaboration, India-CMS meeting, Delhi Univ, 27-28 March 2009

  9. Status of India-CMS tasks AG: Report to the Collaboration, India-CMS meeting, Delhi Univ, 27-28 March 2009

  10. T. Virdee CERN/Imperial College Details in Talks by Coordinators AG: Report to the Collaboration, India-CMS meeting, Delhi Univ, 27-28 March 2009

  11. Summary of HO commissioning (details from KS/SRD) • HO is installed and commissioned • Known that HPDs have problems: for HO cross talk (misalignment of electric and magnetic fields) as well as discharge. • Overall plan to replace HPDs with Si-PM readout, for all HCAL. As problems for HO moving wheels (rings +-1, +-2) are more severe, proposal to change soon. • As noted, no shutdown in end-2009, so earliest replacement can take place in end-2010 shutdown. • This year placing two RBXs with Si-PM readout, one each in ring 1 and 2, to study performance in real-life conditions. • Also test beam in July 09 with Si-PM RMs AG: Report to the Collaboration, India-CMS meeting, Delhi Univ, 27-28 March 2009

  12. Brief Status of Interventions(report from TSV) • HCAL HB & HE : 19 out of 288 HPDs changed and tested. • 11 due to high rate of discharges at B=0T and B=3.8T • 5 due to gain loss or very low gain • 3 Readout Modules (f.e. electronics) exchanged. • Operating voltage for HB/HE lowered to <7kV>. • HCAL HO (W±1, W±2) replacement programme completed • Operating voltage lowered to <6.5kV>. Aim to install 2 RBX’s with SiPMs (no discharging at all field values) AG: Report to the Collaboration, India-CMS meeting, Delhi Univ, 27-28 March 2009 12 T. Virdee CMS Week Dec08

  13. Si-PSD (BARC report) • All sensors fabricated and module mounting done and shipped to CERN • Installation of PSD within CMS detector was scheduled in February/March 2009 • Going on successfully AG: Report to the Collaboration, India-CMS meeting, Delhi Univ, 27-28 March 2009

  14. Some Photos:Installation of the Preshower AG: Report to the Collaboration, India-CMS meeting, Delhi Univ, 27-28 March 2009 14 T. Virdee CMS Week Dec08

  15. Preshower • Much progress since Dec CMS Week • All 4 Dees are ready for installation • System tests done at +15C and -15C, 0.015‰ channels dead! • Installation platforms delivered on time • Infrastructure for ES+ ready, for ES- in March.Final off-detector readout cards (ES-DCC) expected in May. • ES+ moved on 26 Feb, installed underground and attached to support cone. Finish ES+ commissioning by end March • ES- moved on 12 Mar, installation starts this week, aim to finish commissioning by Easter One Crate/plane: 4 FEC-CCSs, 10 ES-DCCs AG: Report to the Collaboration, India-CMS meeting, Delhi Univ, 27-28 March 2009 Well Done to All Involved

  16. Preshower: Photos Transporting the ES+ towards EE+ The two separate ES+ Dees AG: Report to the Collaboration, India-CMS meeting, Delhi Univ, 27-28 March 2009 ES+ attached to support cone 16 T. Virdee CMS Week Dec08

  17. GRID Tier-2 Centre(details by KM) • All hardware purchased and most is commissioned • All technical tests passed successfully. • Recall that we have TIFR-CERN point-to-point link and in CMS computing model Taiwan is our Tier-1, NOT CERN. • (Also working towards connecting this 1 Gbps link to the European GEANT network which will allow general internet access and not exclusively to CERN) • After much delay (11 months) European Commission (via Dante) agreed to peering of our line to GEANT. • Thus, we now have high speed connectivity to many Tier-1 centers and the requisite number of up- and down-links have been established to qualify as a regular CMS Tier-2. AG: Report to the Collaboration, India-CMS meeting, Delhi Univ, 27-28 March 2009

  18. RPC affairs • OLD: • Not only low η, but also high η RPCs have to be built as part of the “endcap-RPC restoration” program for CMS. For high η the deadline is end-2010. • It is now confirmed that India can expect to participate in the overall program and the real deadline for us is end-2010. • DU withdrew from the India-CMS RPC project, leaving BARC and PU. • NOW • Effect of delay in LHC: forwards RPCs expected to be installed during 2012-13 long shutdown (not in 2010-11 shutdown). So time is very comfortable. • Next slide: some (minor) problems to be sorted out. AG: Report to the Collaboration, India-CMS meeting, Delhi Univ, 27-28 March 2009

  19. Areas of Concern Not Major Endcap RPCs: Some chambers, especially in RE-2, showed increasing leakage current – progress being made. Still collecting data. Soon determine strategy to follow. AG later discussion with Archana, Jim Virdee: problem occurred inside CMS detector environment (temp? humidity?). Once outside (ISR hall) some seemed OK again. Being investigated. But new chamber production will starts only after this is understood. Magnetic Field:fringe field, modeling and flux in return yoke Forward Region:TOTEM, ZDC, CASTOR etc. ECAL: Work ongoing to recover other Trigger Towers, Off-detector Electronics: EE_TCC48, ES_ DCC Others: manpower, sustained operation, SLHC upgrades and the required facilities …- being dealt with – but more to do. AG: Report to the Collaboration, India-CMS meeting, Delhi Univ, 27-28 March 2009 19 T. Virdee LHCC Feb09

  20. Endcap RPCs Current Increase RE+ chambers were switched on in the cavern for the first time beginning of September. HV was applied after about 100 gas volumes exchange. The gas flow was set to (1 volume)/ (2 hour). In a few days a significant increase of current was reported on several channels. Situation for gaps RE+2 down (about 40% of HV channels reported an increase) < 0.5 mA/day < 1.0 mA/day < 2.0 mA/day > 2.0 mA/day AG: Report to the Collaboration, India-CMS meeting, Delhi Univ, 27-28 March 2009

  21. RPC’s Endcap RPC’s Preliminary Conclusions RE chambers show larger than expected sensitivity to temperature. Similar measurements on the way for barrel chambers. Stability of cavern humidity and temperature should be achieved for a safe RPC running. An installation campaign of T and RH sensors (both environmental and gas) has been launched Increase of current at P5 partially reproduced at ISR. Careful investigation to spot other causes Final brainstorming expected middle March to revise the results and take action. A possible parallelization of the gas circuit will be discussed. RPCs Noise Susceptibility Spikes observed during CRAFT data taking. The chambers are susceptible to noise generated by the flickering of fluorescent and projector lamps in the cavern (with magnetic field on). Star washers on the chamber front panels and additional shielding appear to help. More work needed. AG: Report to the Collaboration, India-CMS meeting, Delhi Univ, 27-28 March 2009

  22. General, CMS-week related AG: Report to the Collaboration, India-CMS meeting, Delhi Univ, 27-28 March 2009

  23. Reminder from Dec Week: Interventions • NB: the CMS detector was/is in good shape to have taken high quality collision data. • Maintenance is an ongoing process. • Areas of Intervention Under Discussion • Tracker: Cooling system, Fpix. Review soon before proceeding. • HCAL: a few HPDs in HB and HE. Several in HO (W±1, W±2). • Muon DT/RB: ~ 10 chambers to be repaired, start & gain experience with YB0 +side and then proceed, the one that is most difficult. • CSCs - repair ~10 chambers previously known to have faults but were inaccessible due to logistics of disks in 2008. • Alignment Components: protect sensors/MABs, repair DCOPs,... • Endcap RPCs: Some chambers show increased leakage current - under investigation. Work is going reasonably well. We are within a few days of the schedule defined in mid-Nov. Vigilance is paramount.

Electronics and Electrical Systems Review • Goal (w/s 19 Jan)Go through the operational experience with the electronics and electrical systems, • Identify any problems, including sensitivity to noise, • The reliability of the systems, the availability of spares, plans for Upgrades. • Conducted by M. Hansen and P. Sharp (with other experts). Main Conclusions Over All CMS Electronics Operated well during the CRAFT Global Run. However there are some Issues: • There is a Serious Shortage of Firmware Experts and the Development & Maintenance of Firmware will remain an Issue for the Life of CMS • All Sub-Detectors need to have access to a well Maintained Integration Centre in B 904. • This Centre should Continue to be used to ‘Sign-Off’ all Changes to Hardware, Firmware and Software before they are deployed in CMS • The Facilities at B 904 should involve ‘End to End’ Systems including the Trigger and DAQ AG: Report to the Collaboration, India-CMS meeting, Delhi Univ, 27-28 March 2009 T. Virdee CMS Week Dec08

  37. Electronics and Electrical Systems Review Other Conclusions • Emphasis should be given to ensure that all systems have both the People and Documentation to maintain the systems throughout the life of CMS • Institutional Commitment • New Systems must be Reviewed to ensure that they are Safe and have no impact on existing Systems • Pre-Shower, Totem, Castor, ZDC • All Changes to Existing Systems Must be thoroughly Reviewed to ensure that they are Functionally Correct and Well Engineered • Vigilance in Controlling System Noise is Essential • RPC & New Systems • System Problems and ‘Down Time’ must be logged and Reviewed • ES DCC production issues and EETCC production and commissioning will require close monitoring AG: Report to the Collaboration, India-CMS meeting, Delhi Univ, 27-28 March 2009 T.

Plan a presentation on pixels in Mon Plenary of the next CMS Week • Whoever is interested has an opportunity to participate. • Phase II • A few areas where big decisions have to be taken which have serious implications for CMS as a whole: e.g. Tracking/L1 TriggerECAL/HCAL/Trigger – also End-cap calorimetry in general. Cross-subdetector work. • Whoever is interested has an opportunity to participate. • Engineering Issues (New TAS/FIN, cooling, Forward Region, BCM/BLM, YE4) • Radiation Issues • Funding: In addition to R&D and construction costs need to fund the TC Project Office, Engineering Centre (System Engineers – Mechanical and Electronics), Facilities such as 904,… • Cost Book + Cost Reviews AG: Report to the Collaboration, India-CMS meeting, Delhi Univ, 27-28 March 2009 T. Virdee CMS Week Dec08

  39. Report from LHCC Referees (17 Feb Meeting) • Detector Construction, Maintenance and Repairs • The referees congratulate CMS for their careful planning and impressive progress …. to produce a complete, reliable detector for the upcoming long 2009-10 run. • Once again taking the long-term view has paid off for CMS, and should put the experiment in good stead for the unusually long and important 2009-10 run. • ….. the puzzling loss of flux in the return yoke - look forward to the answer at a future meeting. • Preshower • The preshower detector was completed and comprehensively tested on the schedule presented in November. Bravo! • TOTEM Issues (combined session with TOTEM and its LHCC referees) • The referees identified several issues of concern that are now being worked out among CERN management, CMS, and TOTEM. • The guiding principle established is that TOTEM elements must be subjected to the same standards and reviews as were CMS subsystems before they are allowed to be installed in CMS.

  40. Report from LHCC on 17 Feb. • Detector Performance, Computing and Physics • CMS physics organization has provided outstanding leadership and planning, which has helped advance CMS to an unusually mature level of preparedness for physics. … efforts underway to improve reliability of T1 and T2 sites … • …. great progress toward achieving TDR performance specifications…… • We support the approach of developing the PAT tools and a standard framework for CMS analyses. Experience at the TeVatron and the B Factories has shown that a common “language” like this has been of great benefit in producing physics results that can be easily understood, and rigorously evaluated within the collaboration. … • We were impressed by the several analyses presented of simulated data, including measurements of top, searches for Higgs, exotics, SUSY, and the other “standard candles” … • In this as in the other areas of preparation for beam and physics, CMS is in excellent shape. • Very encouraging report BUT we (CMS) should not get too carried away. These nice words will not mean much if we cannot rapidly produce good physics results when the real moment comes. • We must maintain our focus and continue striving to do better.

Education and Outreach • Current core activities : continued production of the CMS Times and the evolution of the Outreach web site (11k distinct visitors/mo). • Recent Activities • Several new "virtual reality" movies of CMS underground, • Archiving thousands of superb images of CMS (please send your most interesting photos to Lizzie (elizabeth.gibney@cern.ch) • New online version of the CMS Bulletin, hope to release during June CMS Week. • Release of the Hollywood movie ‘Angels and Demons’, based partly at CERN. Much activity in the US, CERN e.g. public lectures. CMS planning to hold one such evening at Point 5 with a guided visit to UX. • Setting up CMS alumni group (with CERN) to keep over 1000 CMS ex-members in touch with CMS news, events, developments and each other. Possible to upload articles, receive e-newsletters on latest developments and network. • Looking Ahead • Create two new exhibition centres: one at Point 5 and one next to the CMS Centre (Meyrin). Use spare parts of the detector incorporated with modern technologies, such as large touch-screens and "virtual reality" movies. • Education: sharing data/simple analyses in schools and undergraduates in Uni AG: Report to the Collaboration, India-CMS meeting, Delhi Univ, 27-28 March 2009 MB Mar 09 tsv

  47. Miscellaneous Publishing CRAFT Results Many people across the whole Collaboration contributed to the successes of last year, including the CRAFT run and its data handling and analysis. Results are very encouraging. The whole Collaboration should sign this. Should publish before LHC startup. Discuss whether to publish as a single paper or several, suitably linked, in one volume ? Choose whichever path is most efficient. To discuss. AG: Report to the Collaboration, India-CMS meeting, Delhi Univ, 27-28 March 2009 MB Mar 09 tsv

  48. Issues for this India-CMS meeting • Decision on new groups • Organizational matters: soon going into M&O (data taking + physics mode) (good idea to rotate, but same one can continue) HO M&O, calibration etc of current detector, future towards Si-PM Si-PSD  M&O, calibration etc of current detector RPC  detector fabrication by end-2012 GRID, Tier-2/3  connectivity from T2 to T3 soon, integration in CMS-GRID network: Vipin, Kajari, Sudeshna, Raman, Satyaki, Manas. All these be in Task Force. Physics  activity increasing rapidly Coordination, coordinators. (Current: HO-Sudhakar, Si-PSD-??, RPC-LMP/JBS) AG: Report to the Collaboration, India-CMS meeting, Delhi Univ, 27-28 March 2009

  49. Issues… • Discussions underway in CMS on detector upgrades for SLHC, timescale 4-5 years from now. • Keep in mind we have already 2 hardware projects on our hands/consideration: Si-PM in HO, and RPCs…. Still…. • Budget: spoke with Mr Vijayraghavan (26 feb, 25 mar, also rks and kailas spoke to him). Both CMS and GRID are with DAE-Finance, he expected 7-10 days from 26 feb…. Says he will push again. • Next meeting… 31 July, 1 Aug, BARC, Mumbai… • Mailing list… WEB page… AG: Report to the Collaboration, India-CMS meeting, Delhi Univ, 27-28 March 2009
