HF UPGRADE PROJECT

1. HF UPGRADE PROJECT Y. Onel PM Sept 3, 2012

2. Recent Highlights and News-I • The PMT deliveries are now completed. Testing is going well. We had a meeting with Hamamatsu regarding our reject tubes. We have shipped back about 25 PMT’s ( low gain, high dark current and black cover problems) to be tested by them. We have shipped about 1000 PMT’s to CERN. 2nd900 PMT sorting is now completed and George et al will load the info in the HCAL DB. The PMT and Base Boards System tests with a QIE system has started at CERN-904. • We have approved the Base Board Production. (Reports from IOWA and CERN Tests are available) • Worked on the New HV system and formed a committee to evaluate the RFP responses.. Received a detailed report from German and Alexi.Both power supplies (CAEN and Bulgarian) were tested and evaluated at CERN E-pool using professional equipment and high expertise level of pool technicians. • The HV RFP and decision committee members are: Germain, Alexi, Ianos, S.Los, M.Miller, D.Winn from HF and Magnus and S. Lusin from CMS Coordination. The charge to this committee is written and we had our committee meeting on Friday August 3rd. The information provided by the HF Upgrade group was well received. There were some questions regarding Dynode 9-10 powering “Synchronization “ in the base board –S.Los has responded to this question. The decision is taken by this committee and we received the final recommendations by the PRR Committee. • We have decided on the shield length- 54 mm (looks good !! the presentation by Ianos during HF meeting on May 14th ) and got confirmation by Pawel. Mike Fountain has started with the production.

3. Recent Highlights and News-II There is an agreement for a new cable purchases– Thanks Chris Tully, Jeremy Mans and Pawel De Barbaro for this. There is also a strong support from Austin and Magnus on this. Special thanks to Joel helping on this. HF new front end integration was presented by Ianos to the HCAL as well as to the CMS TC. The HF Electronics Packaging as well as the agreement within HCAL that we should pursue the Winchester Cables presented by Terry Shaw. Terry Shaw and Ianos have finalized the specs and they will be getting the quotes soon. Developing our “Project Org Chart” adding Brazilian Universities and ITU, Istanbul. Alberto Santoro and Gilvan-Augusto Alves are named as Co-L2’s for Brazil in our org chart. E.Gulmez BU-Istanbul is L2 for Turkey.

4. OLD PMT vs NEW PMT Old PMTs(idleseveral years) exhibit systematic gain loss vs Integrated Luminosity, rate of loss slowing down. New PMTs (burned in) (24 installed in Feb-2012) show no signs of gain changes so far (3mo, ~6fb-1) HCAL Operations report CMS Week June 2012 Pavel Bunin, JINR, Sudan Paramesvaran, https://indico.cern.ch/getFile.py/access?contribId=1&resId=0&materialId=slides&confId=195406

17. HF Schedule Gantt Chart

18. HF Upgrade Project Funding FY 2013 • We will provide an excel file describing of our request for the LS1 operations and the details of new HV system cost estimate. • PO Change order 21K ( for PMT Shipping and and dark-boxes, cables, an additional ROBOX machining and material)-Done-Thanks • Need new HV budgeted in the project files • Need new cables budgeted in the project files • Need a minimum of 200 additional PMT’s to meet DOE “Spare” 15% guidelines LS1 2013-14

19. Cable & PMTs

20. New HV System (CAEN Solution 1)

21. ROB with new adapter boards and recessed connectors

22. Components of new design Upgrade HF ROBOX Base board + adapter board New signal connectorsand/or connector support Plate2 (G-10) Sleeve PMT + socket Plate1 (Grade XX Garolite) Shield Kapton insulator

23. Summary of components Depends on cabling decision and final cabling connector specs. Expecttoplace order by Oct1 * Production will be in batches spread out over the year. Expect >3/4 done by fall. Finished by end of year, but have few months contingency in early 2013.

24. Winchester cabling solution Consists of 3 parts: • Cable for inside PMT Boxes, • 5m cables to FEE, • Adapters to connect to existing FEE

25. Assessment of Winchester cables mechanical properties Four complete sets of cables were provided in advance of the October 2011 testbeam period. • Diameter of cable ~2cm. • Minimum bend radius of ~10cm easily attained. • Cables are robust, and very pliable. Suggested improvements: • Cable is stiff at the shrink tubing used to terminate the outer sheath. This could present some difficulties if too long as tightest bends are required near the ends of the cables. • Would prefer longer and knurled connector nuts so that they could be turned by hand without need of a screw driver. • Over tightening of jack screws on the existing D-sub connectors has been a persistent problem. • Cable connectors should be identically keyed so that cables can be easily swapped. Very important for rapid trouble shooting and fast cable replacement if necessary. • Would like grips on cable connectors to ease connecting/disconnecting. • Would like protection of the contacts to prevent damage during handling and installation. • Modifications discussed with Winchester in July. Essentially excepted.

26. HF QIE Card

27. HF Card concept Dual QIE board unit 2x24 channels =48 / unit 6U crates with 1.2” module spacing.

28. Cable integration • Cable volume will substantially increase • Detailed evaluation was performed to confirm that the proposed solution was feasible given the space constraints within the HF shielding and support structures • (also for 4-anode readout). Upper level cable storage shelves Cable exit port in shielding Critical choke point Lower level cable storage under floor Cable storage areas remain accessible when HF’s are in garages. - keeps HF cabling off critical path of UXC activities. Cable at front of racks Critical choke point

29. Schedule Scenarios • Purchase of the cables is subject to the spending profile • Scenarios: 1) Purchase all cables within the next 3 months and be ready for installation during LS1. Later on, FE Electronics replaced. 2) Purchase cables for single quadrant within next 3 months, Delay purchase of remaining cables into 2013, but in time to install at end of LS1. • Requires investment in infrastructure for testing/burn on the surface. • Pushes cabling and commissioning to end of LS1. • Put cable purchase off for X years, and install cables at time of FE electronics upgrade. • Uncertain when this could happen. • Big job, risky for a short shutdown.

30. Current status • Meeting with Winchester July 25 • - Make quote good through Oct.2012. • - Two quotes, one for total cable purchase, another for all pigtails, and 50 long+adapter cables. • - Essentially accepted list of modifications. • - Delivery time of 3+ months. • - 75 ohm board mount connectors are in production (will be for 10 years). Simulation to be performed by Winchester.

31. Readout boxes on HF There are 36 readout boxes on each HF for a total of 72 boxes. Boxes are located at a radius of ~1.3m from the beam axis. Each box houses 24 PMT’s and serves ~ a 10 degree slice of the detector. (total number of PMT’s on HF is 1728) All of these boxes are to be dismounted, reworked on surface, tested, and remounted.

32. ROB work flow Remove boxes from both HF’s UXC • Work starts as soon as HF’s are in garages and boxes accessible. • Refurbishment will happen in SX5, HCAL alcove • Boxes will be processed in groups of “quadrants”, 9 boxes that make up 90 degrees in phi on HF. • Boxes will be remounted and commissioned by quadrants (Smallest unit due to shared HV). • Burn in and commissioning happens whenever services are available. • Off critical path. Have flexibility here RP screening Disassembly Refurbishment USC Testing Remount on HF’s UXC Testing/burn-in, commissioning Sourcing

33. Cable work Reception of cables Installation / modification of cable storage Inspection, testing (continuity, & mapping) Including other CMS subsystems Cleaning and consolidation of existing cables and services • Cabling will be performed in units of quadrants. • Ideally cable prep, and installation work is pipelined with ROB work to maximize testing, burn-in, and commissioning in the UXC. Labeling/bar-coding Remove existing FE cables Bundle, installation prep. Re build rack cable supports Estimate 1 week to cable a quadrant, two weeks for first one. ( 9 weeks total). Cable installation ROB install Testing, Commissioning

34. Work area Cable routing and storage At upper level racks Scaffolding for access to boxes and cables Readout box removal/install, Cabling inside outer shielding (ROB area) Cabling at racks Protection from activated areas may be needed Cable routing and storage under floors Removal of collars, CASTOR table. Sourcing: will require ~1 week/HF where access to garages would limited

35. SCOPE • HF work to be done during LS1: • PMT Replacement • Cable upgrade for new FEE (part of LS2) • HV PSU Installation • 2

37. ROBOX Work Flow • LS1 Start: Feb, 11, 2013 LS1 End: Nov 24, 2014 • PMT Replacement: 27 Feb 2013 - 25 Mar 2014 • HV PSU Replacement (USC): April 2013 • Bring HF+ to its nominal position: 10 Sep 2014 - 22 Sep 2014 • Bring HF- to its nominal position: 18 Sep 2014 - 30 Sep 2014

38. HV Installation • We plan to finish HV power supplies installation by May 1st, 2013 latest.Thisis based on the estimate that mid May could be the earliest to power the first HF quadrant. • Also based on availability of CAEN PSUs. • Alexi M. and + helper will finish the installation • German M. will commission the new system with existing PVSS. • ~1 week to do installation. • ~1 week for commissioning. • This planning assumes that the HF HV patch panel and interlock interfaces have been produced, tested, and ready for installation (as well as CAEN system).

39. LS1 Cabling • We planned to benefit from LS1 to do as much as possible to prepare HF • for the future upgrade (multi-anode readout). During LS1 we target for the • following objectives: • Consolidation and clean up of cables and services. (~8 weeks) • Includes removal of existing front end signal cables • Includes the time spent on cables and services from other subsystems. • Modification, preparation of HF structures for cable • storage (~2 weeks) • Prepare racks as much as possible for future electronics. (~1 week) • Could be absorbed in consolidation step above (~8 weeks) • Install new cables (~1 week/quadrant + 1 week for first one = 9 weeks

40. Base Boards • • 80% of Sockets are assembled and tested • • 20% of Adapter boards are assembled • • Base boards should arrive from assembly house by Sep. 10 • 1. 80% of PMT sockets are assembled and tested • 2. 20% of Adapter boards are assembled • 3. Base boards have to be delivered from assembly house by Sep. 10 • Further production plans As soon as we have Base boards from assembly house stop Socket assembly and switch to final assembly/testing of Base/Adapter board sandwiches (by that time we should have enough sockets for installation quantity of the boards – 216) • • 216 sets for installation should be ready by Dec.01 • S.Los recommends purchasing the second set of board-to-board connectors for the future multi-channel Adapter board, before they become obsolete (~$3K)
