Update on TBL Status: CTF3 Committee Progress as of September 17, 2009

The latest status update from the TBL status CTF3 committee as of September 17, 2009, highlights significant progress in the commissioning and testing of the beam. Achievements include a beam current of 10 A and extraction of 20 MW at 12 GHz, consistent with theoretical predictions. Key developments include successful commissioning of instrumentation, handling of beam optics, and addressing electronic issues with BPMs. Future steps involve commissioning higher currents and improving BPS performance, with a shutdown scheduled for October to finalize the beam line.

  1. 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

  2. TBL run with 7 A but long bunches suspected BPM 150 to predict BPM 310 to predict

  3. TBL run with 4 A and good agreement BPS 210 to predict

  4. TBL run 15.9. with 10 A into the PETSForm factor 0.9 Good transmission but noisy signals from the BPS’s

  5. TBL run 15.9. with 10 A into the PETS Optimized for peak power, Form factor = 1

  6. 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

  7. Status on BPS’s from IFIC Valencia Angeles 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
