  1. HIGHLIGHTS OF LAST MONTHS OF HSS ACTIVITIES AN EXCITING AND HECTIC PERIOD WITH THE LHC BACK IN OPERATION… ABP General Group meeting - HSS

  2. LHC: back in operation • Contribution to commissioning scenarios (with HSC) • Preparation of optics for Run II • Contribution to beam commissioning and machine co-ordination Protons and ions First beams on Easter Sunday… ABP General Group meeting - HSS

  3. Optics under control Peak beta-beating below 10% for beta* between 40 and 80cm ABP General Group meeting - HSS

  4. Second life for on-line model • The Run 1 Java framework updated to follow the control system upgrades • Aperture Meter and other apps online

  5. …with new applications and tools • New Java library that interfaces all relevant datasources (LSA, logging and measurements DBs) to build LHC MADX models • Optics, knobs settings, orbit, measured parameters, misalignments, magnetic errors, etc. • It allows to build specialized tools quickly • Modelling of orbit and beta beating • Builds LHC MAD-X model corresponding to a given moment in time • Performs special analyses, e.g., Q’ vs. MO strength

  6. SPS: still no need for action… • No activities to mention, yet. But…collimation project will start taking part in studies for the SPS. ABP General Group meeting - HSS

  7. PS: in good shape as usual… • Contribution to overall beam commissioning and studies (with HSC). • MTE commissioning: • Identified source of fluctuations in beam trapping into stable islands • The beam has been sent to SPS and extracted. • It will be used for the FT physics soon, while optimisation continues in the PS and SPS ABP General Group meeting - HSS

  8. Projects/studies: business as usual… • Collimation: LHC activity - beam commissioning • Commissioning of the system without and with beam • New post-LS1 system: 30 collimators changed/added • New BPM collimator design • Successful commissioning of the system, very good cleaning performance. • Strong support to OP for all new configurations. BPM button ABP General Group meeting - HSS

  9. Projects/studies: business as usual… • HL-LHC • WP2 (beam dynamics) • Optics studies: • New layout just released (HLLHCV1.2) • Advanced concepts • Tracking studies: • Field quality of new magnets analysed and target error tables available • Analysis of ripple in power converters • DA computation for operational cycle Now: contribution to the Technical Design Report ABP General Group meeting - HSS

  10. Projects/studies: business as usual… • HL-LHC • WP5 (collimation) • Strong participation to HiRadMat tests: tested 3 full collimator jaws, 1 for LHC and 2 for HL (new materials) • Complete work for TDR, with updated baseline for DS collimation • Improved design of hollow e-lens, started construction of gun to be tested at FNAL. • WP8 (machine detector interface) • Analysis of failure scenarios relevant for experimental insertions Now: contribution to the Technical Design Report ABP General Group meeting - HSS

  11. Projects/studies: business as usual… • HL-LHC • Ions: specification of beam parameters for input to LIU • LIU-PS • Coordination of activities • Studies of resonance compensation in the PS (other activities in HSC or in collaboration with HSC) Resonance 8Qv=50 excited by space charge: issue solved by changing the integer tune ABP General Group meeting - HSS

  12. FCC Horizon 2020 Design Study Proposal approved by EC ! Future Circular Collider (FCC) study FCC Week 2015 Washington DC 340 participants FCC study now: 61 institutes from 23 countries & CERN addressing key aspects of FCC-hh • Site investigations: • 90 – 100 km fits geological situation well • LHC suitable as potential injector updated FCC-hh luminosity vs time over 24 h, 2 phases Goal: ~20 ab-1over 25 years updated FCC-ee luminosity vs c.m. energy FCC-hh & FCC-ee: compatible layouts 2 reviews held in June 3 reviews in Oct. & Nov. FCC Week 2016 in Rome

  13. Computing: steady increase of activities Contributors are welcome! • MAD-X • Service to the users • Refurbishment of code • New physics or improved models(required for new projects/studies) • SixTrack • Service to the users • New physics or improved models (required for new projects/studies) (also with HSC) • Incorporation of features of general interest developed by users for private versions • Harmonisation of collimation version of SixTrack and standard version ABP General Group meeting - HSS Google summer student programme provided efficient help!
