  • Commissioning structures with 10% more voltage than nominal


  • Circuit model amoust complete, losses still have to be included
  • Detailed presentation next meeting
  • Measurements on the CCDTL planed


  • High Power Test ongoing
    • Operating with 50Hz and 1.5ms pulses. Break downs observed
    • X-ray measurment done (waiting for data)
    • Max temperature: 70C at 3l/min water flow rate
    • CW run with 24kW over weekend


  • High frequency chopping causes a significant emittance growth, if Qex exeeds 105. Only certain high frequency chopping patterns are foreseen in SPL operation and can be fixed. This would allow tuning the HOMs away from resonance lines with slight cavity design changes.
