Time Phase Resp Approx elapsed time
Monday 18/Tuesday 19 Dry Run    
Tuesday - Thursday Magnet tests - S78 and 81- as available - PGC tests first    
Tuesday Final tests with LHCb    
Thursday - Fri

The patrol will take place, during working hours, on Thursday 21 August and/or Friday 22 August.
Experiments out by 14:00

 Laurette/Rossano  
Friday pm Access system - Beam ON    
14:00 - 15:00 Access intrusion/LBDS tests Thomas Ladzinski
Brennan Goddard		 1 hour
15:00 - 16:00

Final prep of TI8 and EIS, final beam interlock tests

 Rossano, Bruno/Ben 1 hour
16:00
  • Beam on to TI8 TED
  • MSI etc pulsing
  • Cycle LHC Sector 78 & left 81
  • Time in kicker
 OP 1 hour checks - trajectory etc.
~17:00
  • TI8 TED out, beam to TDI, kickers off
  • Give LHCb 20 minute warning before taking TED out
  • Kickers on, time in, position checks, resolve any timing issues
 INJ TEAM 1 hour
~18:00 TDI out - threading - momentum matching - beam to IR7. Jorg & team 3 hours
Over night Fri-Sat Kick-response measurements, optics checks (no preemptive aperture checks)
Take response data across end TI8 and p8 injection region using last corrector in TI8 		Jorg & team 8 hours
Fri-Sat Dispersion measurement
Measurement of dispersion function at end of TI8 and across injection region		 Verena  
08:00

re-cycle

 1 hour  
09:00 Meeting    
Sat am

BPM system - capture mode, intensity dependence

Timing-in without beam of LBDS system in inject and dump mode - parasitic - (for a quiet moment)

Rhodri, Lars

Bren

 3 hours
  re-cycle S78    
Saturday evening/overnight

Gentle aperture measurements combined with beam through IR7, BLM response IR7 re-check optics if required.

Dispersion measurement through IR7

Injection screen measurements in parasitic mode (VK)

Stefano & co

Bernd & co

 8-10 hours
09:00 Switch to TI2, re-cycle    

Sun.

(finally started 15:00 going to take 4 hours minimum)

 SECTOR 23 revisited - dispersion through IR3 (increased intensity)- kick response revisited
[2 10^9 into a magnet]		 Ops

6 hours

ALICE is informed that TI2 injection to point 3 will take place this week-end, on saturday, from about 14:00 to 19:00, with probably little time spent on TED and TDI (<20 min) and using first 2e9 probes then possibly 5e9 probes for the actual optics measurements.
  Back to S78    
Sunday evening 19:00

Finish Polarity checks etc

 Frank & Mike & co 5 hours
21:00 Phase advance with trimmed main quads John Jowett 3 hours
23:00 Re-cycle - reset    
Sun night

Injection region aperture checks (3 hours)

Measurement of MKI waveform using beam position response on injection screens - dedicated measurement with TDI closed to 'protect' setting (2 hours)

 Bren & team 4-6 hours
06:00 End test    
08:00 Start radiation survey, establish zones (areas which have seen beam) RP All day Monday
