1
Status of ABT beam tests preparation 9-Oct-14
2
Preparation of sector test without beam I MKI: – Open valves, conditioning to 55 kV, softstart – Check BETSsim input, SMP energy transmitted – Check MKI waveform logging in OASIS, IQC Magnet systems: – Heat run – Pulsing full line – Switch powering BI systems: – Movements, acquisition, logging, fixed displays – Screens, BPM, BCT, BLM – SPS extraction region, TL and LHC injection (Francesco, Jose) – LHC extraction region (Matthew, Jose) Needed for TL test, 22-Nov Might have issue with TI 8 BLMs for TL test
3
Preparation of sector test without beam II Optics – Prepare list of settings for SPS extraction: Kicker nom/max voltage, Septum current/girder pos, bumper currents (Francesco, Jose) TL and LHC injection: MKI nom/max voltage, MSI current (Matthew, Jose) LHC extraction: MKD max/nom (6.5 TeV), MSE current (Matthew, Jose) – Beam position on injection/dump region screens SPS extraction and TL screens (Francesco) Injection screens (Jose) Extraction screens (Matthew) – TCDI and MKI validation knobs, 14/15 MKD extraction knob Prepare TL phase oscillation knobs every 30 deg (Francesco) MKI knob (Francesco, Jose) MKD knob (Matthew) – Aperture bumps at MSI, TCDIM, MKI, Q5, D2, TCDQ Prepare screenshots of aperture bumps in YASP – Screens matching application
4
Protection devices TCDI, TDI, TCLI, TCDQ, TCS – Movement, function/range – Prepare list of gap opening in sigma, beam size at each collimator (different energies at TCDQ/TCS) – TCDI (Francesco) – TDI, TCLI (Jose) – TCDQ, TCDS (Matthew) Interlocking – Downstream TED master BIC, injection permit TT40 – Inhibit of MKE in case of MKI erratics Need ‘dummy’ TCDI settings for automatic setup check at TL test
5
Preparation of sector test without beam III Radiation monitoring – Radmons, Ramses in injection/extraction region – Check variable in the logging Quality checks: IQC, IPOC – Data reception and logging – Element strengths and limits (thresholds to be updated later) Discuss limits with Verena and Lene – Element updates, new BLMs in injection regions Get updated drawings from BLM team – New BETS interlock on MSI, TDI To be discussed in detail Maskable BIS input Access to UA while MSI powered to check HW limits?
6
Preparation of sector test without beam IV Beam dump – Arming sequence with global BIS – LBDS settings and MCS (changes of generators) – BETSsim (Q4, MSD input) – XPOC Waveforms, VAC, BTVDD, BPMD need beam dumped event BLMs – new BLMs and filters BETS interlock TCDQ
7
Preparation of sector test with BIS loop closed New TSU link to BIS Prepare inject&dump
8
Preparation of sector test with beam SPS extraction to upstream TED (Jose, Francesco, Matthew) – Setup pilot cycle, copy/generate settings,… - Verena/OP early next week – Setup extraction bump without extensive aperture scan – Steer through extraction channel – Check beam on screens – Kicker (MKE) timing on OASIS need BCT+MKE Mid-next week
9
TL test 22-23 Nov Planning will be updated Main measurements relevant for ABT – Threading/steering – MKE waveform and TL stability – Aperture scans of lines – BPM/Corr polarities – Rough linear optics – Automatic TCDI setup – MSI/MKI pulsing – LBDS/MKI synch
