The 88-Inch Cyclotron is operated as a national facility in support of U.S. Department of Energy programs in basic nuclear science. The RF system of the cyclotron is based on the quarter-wave cantilever type resonating structure powered by 500kW 4648 RCA RF tetrode operating in grounded cathode configuration. The resonance frequency range of the RF system is 5.5MHz to 16.5MHz. Prohibitive...

23. Klystron Amplifier for Short X-ray Pulse Prototype and Test Set*

Mr Arthur Grelick (Argonne National Laboratory)

05/05/2010, 14:00

The proposed baseline design for the addition of short X-ray pulses at a sector of the Advanced Photon Source (APS) storage ring called for 20 superconducting deflecting cavities, each excited with 5 kW cw at 2815.5 MHz, which is the 8th harmonic of the storage ring frequency. A klystron amplifier has been designed based on a best effort, reduced power, engineering sample tube. The initial...

32. New prototype modulator for the European XFEL Project in Pulse Step Modulator (PSM) Technology

05/05/2010, 14:30

The European XFEL project at DESY in Germany requires 27 RF stations capable of 10 MW RF power each. Each RF station needs one high voltage modulator that generates pulses up to 12 kV and 2 kA with a duration of 1.7 ms and a nominal repetition rate of 10 Hz. DESY decided to investigate new modulator prototypes and Thomson has been awarded to design and build one of these prototype...
