  1. KEK/ISIS/ANL LOI Amplifier/Second Harmonic RF Collaboration Meeting Tuesday, 26th of June, 2007 PAC07, Albuquerque, NM

  2. IPNS RCS RF System Block Diagram:

  3. Third Cavity Installed in L6 Straight Section:

  4. Third Cavity and Final Amplifier: • Final amplifier uses two Eimac 3CW150000H3 water-cooled power triodes in a grounded-grid, cathode-driven, push-pull topology. • Operated Class A. • Plate power supplied by an 8 kV, 24 A DC power supply. • Typical operating point: • Vplate = 8 kVDC • Vgrid = -320 VDC • Zero-signal plate current/tube ~ 5 A

  5. Final Plate Supply, Cavity Bias Supply and Filament and Grid Supply Cabinet: Cavity Bias Supply: 0 to 1000 A DC Final Grid and Filament Cabinet Final Plate Supply: 8 kV, 24 A DC

  6. Predriver and Driver Amplifiers: • Predriver amplifier uses two Eimac YU-106 water-cooled power triodes in a grounded-grid, cathode-driven, push-pull topology. • Operated Class A. • Plate power supplied by a 5 kV, 4 A DC power supply. • Typical operating point: • Vplate= 5 kVDC • Vgrid = +35 VDC • Zero-signal plate current/tube ~ 1 A • Driver amplifier uses two Eimac 4CW25000A water-cooled power tetrodes in a grid-driven, push-pull topology. • Operated Class A. • Plate power supplied by a 5 kV, 10 A DC power supply. • Typical operating point: • Vplate = 5 kVDC • Vscreen = 1.5 kVDC • Vgrid = -300 VDC • Zero plate current/tube ~ 3 A

  7. Timeline: • Summer Shutdown, 2005: Disassembled test stand and moved equipment into place. • Winter Shutdown, 2005-2006: Installed third cavity in RCS. • March, 2006: Operated all three cavities with beam (3rd cavity operated in fundamental mode). • Septemember, 2006: Operated 3rd cavity in second harmonic mode (for first ~4ms of cycle) with beam.

  8. Results with Second Harmonic: Rectified fundamental and second harmonic gap voltage. Single-turn, vector sum of gap voltages, at ~1.8 ms after injection. Bunch profile without second harmonic, at ~1.8 ms after injection. Bunch profile with second harmonic, at ~1.8 ms after injection. Time Injection Mountain range plot starting at injection without second harmonic, duration ~4 ms. Mountain range plot starting at injection with second harmonic, duration ~4 ms.

  9. Future Plans:
