HIGHLIGHTS OF LAST MONTHS OF HSS ACTIVITIES AN EXCITING AND HECTIC PERIOD WITH THE LHC BACK IN OPERATION… ABP General Group meeting - HSS1

16/09/2015 LHC: back in operation Contribution to commissioning scenarios (with HSC) Preparation of optics for Run II Contribution to beam commissioning and machine co-ordination ABP General Group meeting - HSS2 Protons and ions First beams on Easter Sunday…

16/09/2015 Optics under control ABP General Group meeting - HSS3 Peak beta-beating below 10% for beta* between 40 and 80cm

16/09/2015 Second life for on-line model The Run 1 Java framework updated to follow the control system upgrades Aperture Meter and other apps online

16/09/2015 …with new applications and tools New Java library that interfaces all relevant data sources (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

16/09/2015 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 - HSS6

16/09/2015 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 - HSS7

16/09/2015ABP General Group meeting - HSS 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. 8 BPM button
