Buncher cavity

• the cavity arrived in Geneva (not yet in CERN) from Polland (shipment on 2nd February).

DTL

• visit to Bilbao to define collaboration
  • the drift tube parts will be supplied from July 2010.
  • the drift tube for the HP test could come to CERN in a few weeks
• position of waveguides (WGs) and pick-ups on tank1,2,3 are under investigation
• DTL prototype
  • Qloaded about 15000 against 18000 at the time of the HP test.
    • transition N-type to WG to be checked
    • tightness of the bolts on the end-walls to be checked
    • after the meeting the N-type to WG transition was found to be the culprit. The correct Qloaded is 18000.
  • Upgrade of LabVIEW data acquisition from PLC
  • Presentation for LLRF working group

CCDTL

• Circuit Model:
  • simulated modes curves fit with measurements
  • difference between simulated and measured coupling cell frequency: 160kHz

PIMS

• Schedule for construction was relaxed by 6 month
• Decision has to be taken if structures will be welded or brazed.
  • Interesting option could be the brazing because the vacuum brazing oven will be ready at the end of the year and can fit with the schedule
• PIMS low power measurements to be started on the 1st week of March
