Update on TBL statusCTF3 committee 17.09.2009

• Several runs with beam, slowly increasing the current Arrived at 10 A beam current and 20 MW 12 GHz power extracted

• Got experience with beam optics and handling for TBL

• Commissioning of instrumentation, BPM’s, BPS’s, RF-diagnostics for amplitude and phase, movers

Conclusion so far:• 12 GHz production in good agreement with theoretical predictions PETS is well behaved so far, transmission, vacuum• Beam handling rather simple• Some problems with BPM electronics

Next steps

Commissioning:• Higher current : 20 A, 100 MW (delay loop needed)• Better BPS performance to measure resolution and to play alignment games with the movers

Finishing TBL:• Finishing the beam line in the next shutdown 21.9 – 16.10 (all Quads, BPS, vacuum system and spectrometer)• Series production of tanks launched ( Two tanks expected to be installed during the winter shutdown )• Norwegian collaborators expected to work on TBL commissioning in 2010

Status on BPS’s from IFIC ValenciaAngeles Faus-Golfe

Status:• BPS finished, calibration measurements ongoing• Electronic droop compensation by Gabriel Montero next week (week 39)• Juanjo will come to CERN week 41 and 42 to help with the installation
