*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
      *  [[%ATTACHURL%/CERN_DTL_prototypeAvailable.pptx][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
