Status of ABT beam tests preparation

9-Oct-14

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

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

• 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

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?

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

Preparation of sector test with BIS loop closed

• New TSU link to BIS• Prepare inject&dump

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

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
