NB Beam Dumping system covered by Verena here

  Objectives Results Comments
Timing

Check application functionality - tables, events, telegrams, monitoring, energy

  • Test circulate and dump - looping in sequencer
  • Friday: JJG table - first pass
 Standard functionlity from Delphine's application looking good with new additional features such as event monitoring.

 
Injection Kickers
  • On Wednesday - pulse both 2 & 8 to nominal voltage, control from application
  • OASIS
  • Logging of waveforms
  • Start with auto-generated pre-pulse by Etienne
  • Friday - expect pre-pulses from RF - need to check ring1/ring2 logic very carefully
  • GHH application OK, but not using LSA yet.
  • OASIS - problems to track down kicker pulses whe B1/B2 ing
  • Logging of waveforms, if there then rubbish, otherwise missing
  
Injection requests
  • First tests of functionality - to "CBCM"
  • Alternate ring1/ring2
 First attempt at alternate rings via database defined injection sequence (driven from timing application for the moment) looks good Will not do this from sequencer in first year.
BIS   SMP: Energy pushed to timing system and out over cable OK  
Power converters Converters in 2-3 to VS_SIM. Test all usual functionality from equip state

Looks goods but hit QX bug. Unable to drive NESTED and IREF together

Autocommit (i.e. payload and event) still a bugbear:

  • Need this for tim but NOT
  • equip state and sequencer
 Generate actual and ramp and squeeze (7 TeV nominal)
RF   RF: hardware in place (Andy) but not coming out over fibre yet Waiting on pre-pulses on Friday

Collimators
c/o Stefano

 settings- discrete for "open", "coarse", "protect"
settings - ramp
settings - squeeze
Drive - collimators in 3
Drive - lab collimator with squeeze function
BLMs - individual monitors
BG - can Atlas dummy up something?
Temperature
Logging
Fixed Display
Sequencer: drive actual injection settings(HARDWARE defined), check until armed, send timing event (dummy task for the time being), check until idle.
At the end of injection plateau, move out injection protection devices only: check that idle, drive actual settings for injection protection devices OUT, send timing event (dummy task for the time being), check until idle.
  • Drive of collimators in 3
  • Actual settings control looked good from sequencer I have prepared the actual cycles for the ramp cycle "Collimator_testV1":

    ACT@0_[START] -> Nominal start of ramp
    ACT@1         -> Parking
    ACT@2         -> Coarse
    ACT@3         -> INJ-OUT

    The sequence was:

    ACT@_1 --> ACT@_2 --> ACT@_3 --> ACT@0_[START] --> RAMP
  • Ramp (see right) - remarkable
  • Fixed Display - interesting first version
  • Logging?
  • Sequencer OK but soft start of ramps etc
 Picture of first collamator ramp c/o Stefano
BLM
  • Check that last BLMs in transfer lines added to application and logging
  • LHC BLM study buffer working...no application yet though to check
    
DIP
  • Check distribution of timing stuff
  • Check distribution of handshakes
  • Check disribution of beam related stuff

Timing stuff out alright
Handshakes distributed
Enrgy, lumi etc. going out

  
BCT
  • Check acquistion, logging and fixed display
  • Slow BCT looks good.
  • Fast BCT crates not responding
  • Dump BCT crates not responding (expected).
   
BPM
  • Change sensitivity (Equip state).
  • set capture bunch and turns
  • Concentrating threading and capture -
  • Check concentration and write to SDDS.
  • Display from SDDS browser and multiturn application. OK
  • Check that last BPMs in transfer lines added to YASP and logging
  • Have concentrator working for BeamThreading and GetCapData
    
YASP
  • orthoganal steering, threading etc. Interface to LSA settings etc. sound.
   
SCREENS
  • In/out,
  • video
  • sdds
  • fixed display
  • BTVs in injection region; However, cannot move BTVST in point 2, TDI is not baked out
  • BTVs in video channels and fixed displays
  • BTV SDDS logging in TI 2 logging
    
BLMs
  • acquisition
  • concentration
  • logging
  • sdds
  • display
   
FIXED DISPLAYS
  • injection kickers
  • power converters
  • screens
  • BCT
  • Page 1 (mode)
  • etc. etc.
    
LSA
  • Actual settings drive trim with payload and timing event
  • Trim actual physics parameter
  • Trim actual strength.
  • Trim actual current.
  • (plus usual ramp settings - now thoroughly tested)
    
RBAC
  • Vertical Slice to power converters
  • Equip state RBAC enabled and tested
  • other stuff this time?
    
TI8 TED
  • ?
    
FIDEL
  • [Import 23 coefficients and generate transfer functions and harmonics and apply]
  • Auto Trimming of b3 (test example) during decay on injection plateau successfully test [possible]
 Not this time  
SYNC LIGHT
  • Application test
    
WIRE SCANNERS
  • Application test
    
LOGGING
 Full logging of all of above in place.
  • some holes here
  
SEQUENCER Come's in strong on Friday
  • cool for all the beam dump stuff
  • Ok for ramp.. we have kickers, power converters, collimators, LBDS, and some BI.
  

LSA Run Control

(from sequencer)
  • set fill number and push to timing and DIP
  • set mode and push to timing and DIP
  • set bunch configuration push to timing and DIP
  • set handshakes and push to DIP

First test of lsa_runcontrol OK

  • set FN and send to timing
  • set mode
  • set handshakes
