  1. Booster Beam Notching Installation UpdatePIP Talk February 20, 2013 Salah Chaurize

  2. Notching Pre-Shutdown • A 3 bucket gap is created using two kickers located at Long 5 and Long 12 • Notcher – A High Voltage(55kV) Kicker at Long 5 • Noker - Lower Voltage Kicker (20-40 kV) at Long 12 • Used to clean out remnant Notched Beam in buckets At 700 MeV • Beam is kicked vertically into collimator region at Long 6 and Long 13 with upstream gradient magnets seeing some deposited notched beam loss. • The notch timing and synchronization is accomplished by modules in the Booster LLRF Room and local timing modules. • Beam notch for non-cogged cycles occurs at 400 Mev • Cogged notch occurs close to 700 MeV

  3. Notching Post Shutdown • A 3 bucket gap is created using three 1M Long kickers located at Long 12 • 3 Notchers – High Voltage(46kV) Kicker at Long 12 • Notcher converted to NOKA • Noker converted to NOKB • Build/Commission new NOKC. • Beam is kicked Horizontally into new absorber at Long 13 • The notch timing and synchronization is accomplished by modules in Booster LLRF Room. (Same as before) • Extra Wide Aperture BPM and Short Corrector Spool needed. • Beam notch for non-cogged cycles occurs at 400 Mev. (Same as before) • Cogged notch occurs close to 700 MeV. (Same as before)

  22. Need to kick beam horizontally at L12 with beam Nokers to create a notch in the beam. • Current aperture restriction at S12 is BPM plates and upstream and down stream bellows which are all 4.5in. Reason to redesign S12 Spool piece

  23. New Extra Wide aperture BPM will give us 5 in aperture with new spool. • New spool would use some of original spool design without the standard BPM components inside and larger aperture bellows at magnet spool flanges Reason to redesign S12 Spool piece

  24. Extra Wide Aperture BPM

  25. Extra Wide Aperture BPM

  26. S12 CorrectorOriginal Standard aperture 4.5 Inch

  27. S12 CorrectorNew 5” Aperture Spool

  28. Preliminary Results and Commissioning • Using 2 Nokers to create gap in beam at 400MeV • S12 New BPM giving data but needs some gain tweaks • Absorber motion controls working well. • Notched beam loss is currently low due to low intensity running but is as expected.
