2. The IPHI 352 MHz RF source at CEA/Saclay

Mr Abdallah Hamdi (CEA/Saclay)

08/05/2012, 13:30

Oral

The IPHI (High Intensity Proton Injector) is a facility developed at CEA/Saclay in collaboration with CERN and IN2P3. The final step of this Low Energy accelerator prototype designed to accelerate beams up to 100 mA with energy up to 3 MeV is in progress. An overview of the main components is given, the RF source is described and last RF measurements are shown.

30. The SNS MEBT RF Power Amplifier Solid State Upgrade

Mark E. Middendorf (Argonne National Laboratory)

08/05/2012, 14:00

Oral

The original vacuum-tube-based rf power amplifiers (four online, two spare) that drove the four rebunching cavities on the Spallation Neutron Source (SNS) Medium Energy Beam Transport (MEBT) structure have been replaced with commercially available 25-kW solid state amplifiers (4 online, one spare). A 4+1 switch matrix permits remote switching of the spare amplifier into any one of the four...

20. RF power source and distribution at 352 MHz for spoke cavities for ESS and at FREIA

Dr Rutambhara Yogi (Uppsala University, Sweden)

08/05/2012, 14:30

European Spallation Source (ESS) is one of the world’s most powerful neutron sources. The ESS linac will accelerate 50mA of protons to 2.5GeV in 2.86ms long pulses at a repetition rate of 14 Hz. It produces beam with 5MW average power and 125MW peak power. There are 36 superconducting spoke resonators, which provide a power of 0.5MW to the beam. FREIA (Facility for Research...

8. The Advanced Photon Source 352-MHz RF Systems -- A Case for Solid State?

Mr Douglas Horan (Argonne National Laboratory)

08/05/2012, 15:00

Oral

The Advanced Photon Source (APS) booster and storage ring rf systems utilize 352-MHz, 1.2 MW klystrons as final rf amplifier devices. After seventeen years of APS operation, optimized system designs and detailed preventative maintenance activities have resulted in rf system reliability statistics that have exceeded the wildest expectations hoped for at the start of APS operations. How we...

21. The European Spallation Source RF System Design

David McGinnis (European Spallation Source)

08/05/2012, 16:00

Oral

The European Spallation Source Linac reaches an energy of 2.5GeV within 350 meters. The linac delivers an average power of 5 MW with a 4% duty factor (2.9 mSec pulse at a rate of 14Hz). The peak power of the linac is over 123 MW. This averages to a peak power density that must be supplied to the beam of over 350kW/meter. Because of the large power density, 98% of the linac consists of...

11. Operation status and commissioning of four 150 kW SSA on the ESRF booster

Jean-Maurice Mercier (ESRF)

08/05/2012, 16:30

Oral

The operation performance of the ESRF RF system will be presented, followed by a detailed report on the procurement, installation, test and commissioning of four 150 kW solid state amplifiers on the booster.

39. CW RF Systems at the CLS

Jonathan Stampe (C)

08/05/2012, 17:00

Oral

The Canadian Light Source is a third generation 2.9 GeV synchrotron light source which has been operational since 2003. This talk will discuss the booster ring and storage ring RF system architecture, performance, reliability and improvements made since commissioning.

38. Current activities on the rf-system for the proton accelerator facility at PSI

Markus Schneider (Paul Scherrer Institut)

08/05/2012, 17:30

Oral

At PSI, protons are accelerated up to an energy of 590 MeV by two separated sector cyclotrons, the Injector 2 and the Ring. Since 2008 the Ring cyclotron is running with 4 copper cavities. By increasing the cavity voltage to 850 kVp the number of turns was reduced and the beam current is increased up to 2.4 mA, which results in a beam power of 1.4 MW. In 2010 the regular operation suffered...
