Conductor

  5. Corrector Magnet Design • Contract placed with Tesla Engineering - scheduled delivery early August 09 • 20 vertical corrector magnets • 8 combined vertical/horizontal corrector magnets Vertical corrector magnets Combined vertical/horizontal corrector magnets

  6. Standard Ring Vacuum Chamber • Contract placed with VG Scienta - all 16 chambers now delivered.

  7. Injection/Extraction Ring Vacuum Chambers • Design complete • Contract placed with K J Lesker- Delivery due 24th August 09 Kicker Kicker Septum

  8. RF Cavity Progress Input Coupler construction (Times Microwave) • 16 out of 20 cavities received • Final 4 awaiting input couplers from Times Microwave • 2 input couplers have been delivered • Input couplers • Excessive losses discovered on 2 of the feedthroughs and have been returned to Times Microwave for investigation/repair • In parrallel an order for 2 additional feedthrough’s has been placed with Times Microwave due to leaking/damaged feedthrough’s • Cavity evaluation • Four cavities successfully conditioned • Q0≈20000 achieved • Crosstalk seen on the pick-up probe • Responses to be checked and coupler to be adjusted by 180° Cavity construction Tuning range 0- 25 mm EMMA Review Alan Wheelhouse

  9. Progress on Waveguide Distribution Q-Par Angus • Acceptance tests performed on the 27th May 2009 • Issue with the reflected power coupler directivity • 3dB variation with 180° phase shift • Latest improvements look encouraging • To be reviewed • Need to determine its criticality to the LLRF system • System presently undergoing painting • Delivery anticipated by the 30th June 2009 • Installation late August 2009 • Actions • 3dB hybrid required • No flexible waveguide sections • Straight length of WR650 still to be defined EMMA Review Alan Wheelhouse

  10. HPRF Amplifier Progress CPI VIL409 HPRF Amplifier • Software testing and debugging on-going • System testing and debugging on-going • Preliminary results 19th June 2009 • Estimated acceptance test date 13th July 2009 • Estimated delivery 31st July 2009 • Main issue has been resource issues • Delivery early July 2009 • Installation August 2009 • Commissioning September 2009 EMMA Review Alan Wheelhouse

  11. LLRF System Progress • Performance tests performed with I-Tech Libra system • At 5kW (~150kV) per cavity • Phase: 0.0093º (spec is 0.3º) • Amplitude: 0.006% (spec is 0.3%) • Contract for LLRF system to be awarded by 19th June 2009 • Delivery mid August 2009 • Commissioning October 2009 • Critical issue • Synchronisation of the phase with the arrival of the beam EMMA Review Alan Wheelhouse
