Open Action Action / Follow-up
Injection in general:
  • systematic check of aperture in injection region for normal/failures cases
  • installation of Y-chambers (week 15), other modifications (BPM, ...)
  • crossing/separation schemes sorted out ?
  • latest optics known ? Different optics for different schemes ? Impact on interlocking, settings.
  • collection, listing of functional/engineering specs, ECRs, ...
  • reference layout, aperture model, optics in database(s)
  • equipment performance data in LHC database
  • programme for beam commissioning
  • injection sequencer requirements
  • inject-and-dump mode (concept, hardware ?)
 
Interlocking:
  • injection permit loop
  • energy interlocking with SPS, TCDI efficiency (all done ?)
 
TDI
  • vacuum (water vapour)
  • installation/improvement schedule
  • slits between absorber blocs; reduction, model, measurements ?
  • ferrites, the last word ?
  • additional valves ?
  • heat load and cooling ?
  • measured performance (jaw flatness, motor positioning precision, reproducibility, any alignment issues ?)
 
TCLI
  • functional spec ?
  • layout
  • installation schedule
 
TCDI
  • quenches on nearby magnets (all finished ?)
  • TCDIP in TI 8
  • TCDI positions in TI 2, special measures ("passive absorbers" ?)
  • Not realistic to get more TCDI before engineering run - use one TI 8 TCDI for the MSI in TI 2 ?
  • integration re-check in last part of TI 2 (underway)
 
TCDDM
  • nearly ready for installation - NEG coating missing
  • 1 mm error acceptable ?
 
TCDD
  • design status (flange diameter ?)
  • trapped modes studied ?
  • will not come before the engineering run (phase II installation), replacement chamber ok ?
 
TI 2, TI 8
  • database integration
  • aperture model
  • flexibility (comparative study more circuits vs. more collimators)
 
MKI (report in 2 - 3 months)
  • start-up configuration LSS8 + 2, beam screens
  • impedance measurement
  • thermal model, screening needs
  • pulse form, transients ?
  • magnetic performance
 
MSI
  • downstream transition, impedance-wise ok ?
 
Miscellaneous
  • MBSG stray field ?
  • TED formal approval that no cooling stations are needed, report
  • scrapers in SPS
