IT1: LHC Beam Dump

 

Individual systems

System Test
Timing to LBDS
  • BD B1 event triggers dump
  • BD B1 event triggers dump
  • XPOC B1
  • XPOC B2
  • PM supression in inject and dump, circulate and dump
LBDS
  • Monitor: state, IPOC etc.
  • Requested dump
  • Emergency dump
  • Inject & dump
  • Circulate & dump
Dump line BPMs
  • trigger acquistion
  • acquire
  • store & display
Dump line BLMs
  • trigger acquistion
  • acquire
  • store & display
Dump line Screens Acquisition, store & display. XPOC.
Ring BLM Acquisition, store & display. XPOC.
Ring BPM Acquisition, store & display. XPOC.
Ring FBCT Acquisition, store & display. XPOC.
Interlocked BPM Monitor
   
TCDQ/TCS
  • commissioning and tests of low-level controls;
  • connection to interlock system and interlock tests;
  • connection to control system and control tests;
  • tests of setting-up procedures with beam; [centring; beam size; jaw tilt;]
  • pilot -> intermediate Protect -> setting checks
Septa FGC control, load ramp etc.
RF  
BIS

Hw will be probably ready on time. With two issues: - the fibres should be installed - the FESA class shoud be written and tested. In order to allow a remote access by the Sequencer.

  • - Beam permit loops closed with BICs in point 6;
  • - Link between BIS and LBDS installed and operational;
  • - Beam permit loops able to be opened by timing system (programmed dumps);
  • - BIS remotely armed by sequencer;
  • BIC separation
  • PM supression

Software System Tests

   
XPOC
  • Kickers IPOC
  • Dump line: BLM, BPM, Screens
  • Ring: BPM, BLM, BCT
  • Logging, alarms
Sequencer
  • RECOVER
Sequencer
  • INJECT & DUMP
  • CIRCULATE & DUMP
Mode
  • LSA & timing system
Software Interlocks ?
Post Mortem
  • Clear with HWC. Test PM of power converters, BPMs, BLMs...
MCS ?
Logging Of everything, as usual.
Alarms  

Test Use Cases

Requested dump at injection/ramp
  • Send BD1 event and check system response
  • Send BD2 event and check system repsonse
  • Separate BICs - repeat
Inject and dump Sequence & check
Circulate and dump Sequence & check
Recover Sequence & check
