  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
