Injection test - approximate schedule

 

Time Phase Resp Approx elapsed time  
Friday pm Access system - Beam ON    
Friday pm Final prep of TI2 and EiS Rossano 1 hour
Friday 16:00 Final Interlock tests Bruno/Ben 1 hour
Friday 15:20

Beam on to TI2 TED
MSI etc pulsing

Cycle LHC Sector 23

OP 1 hour checks - trajectory etc. Beam down TI2 first shot
Friday 19:00

TI2 TED out, beam to TDI, kickers off

Give Alice 20 minute warning before taking TED out

INJ 2 hours Beam on TDI after correction end TI2
Friday 21:00

Kickers on, time in, position checks

Resolve timing issues

INJ 2 hours Interesting collaboration between timing and RF
Friday 21:40 TDI out - threading - momentum matching - beam to IR3 - beer Jorg & team 3 hours Beam to IR3 first shot. Tweak SPS.
Over night Fri-Sat Kick-response measurements Jorg & team 8 hours

Beam induced quench of RB.A8.L3 at 02:19

Access required to replace quench heater power supply (not related to above quench)

Saturday am Access point 3 & Alice      
15:00-17:00 Steering , RF, BI - beam to IR3     15:00 Beam back to IR3
17:00 - 20:00 Injection region aperture checks - TDI in Bren & team 4 hours TDI in 16:55 - Aperture checks half done
  19:13 Injection kickers - fault off - system reset required - no beam for 2 hours+     22:05 beam back
22:00

Kick-response measurements revisited
IR3 - open collimators - check down stream optics - close collimators afterwards.

Beam trhough IR3 nor problems. Instrumentation & optics look good.

Jorg, Massimo, Stefano   23:05 Beam through IR3
22:00 - 07:00

Gentle aperture measurements

Very nice set of measurements taken over night.

Stefano 8 hours  
09:00 - 14:00

Dispersion plus RF

13:55 - dispersion measurement OK

OP Andy and Philippe   Lots of fun with RF system, crashing counters
and stuff - sorting essential problems
14:00 ish Sunday

Polarity checks etc

(Injection screen measurements in parasitic mode - OK)

Frank 3 hours

Tested BPM response with lower intensity from PS

  • 1 10^9 - not triggered
  • 1.1 10^9 - triggered but noise
  • 2 10^9 - looks good - Rhodri having a closed look
16:00 - finish aperture checks of injecton region
- injection kicker delay scan & trajectory
TDI in
Brennan & co 3 hours Ok
  Re-cycle - reset     followed by problem with quench heater, injection kickers
Sun night Beam through IR3, BLM response IR3, re- check optics

Bernd & co

Stefano & co

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