SPC judgements

Oral presentation

SNS has been operating successfully and ramping beam power steadily to 1.4 MW the design power at 1.0 GeV beam energy. Availability of RF systems has been improved to ~ 95% over the years since commissioning of SNS. Improvements have been made in operation of accelerating structures, RF windows and couplers, and high voltage converter modulators (HVCM) for klystrons for powering nearly 100...

SPC judgements

Oral presentation

Gallium nitride (GaN) RF transistors have higher power handling capacity, higher efficiency and higher operation frequency compared with silicon RF transistors, which makes GaN device a better choice for continuous wave (CW) RF applications. Due to low yield in device fabrication, GaN transistors used to have a much higher price than silicon ones. As a result, high power RF source using GaN...

4. The Advanced Photon Source RF Systems -- Performance and Upgrades, 2012-2014

Mr Douglas Horan (Argonne National Laboratory)

14/05/2014, 10:00

SPC judgements

Oral presentation

Technical performance of the Advanced Photon Source rf systems from May 2012 to May 2014 is discussed. Significant hardware problems and failures affecting rf system reliability, and approaches taken to resolve them, are described in detail. System upgrades to enhance performance and reliability are described. The design and construction details of a 5kW S-band cw amplifier developed for...
