26. High efficiency power source development

Jinchi Cai (CERN)

6/8/18, 9:00 AM

A number of Toshiba's Klystrons E37113 with output RF power of 6MW and 44% efficiency are currently in operation in X-box3 at CERN. To increase the efficiency, thus RF power production of existing tube, whilst preserving perveance and modulator itself, the new design of the HE klystron has been done at CERN. This design is based on the COM bunching technology. However, due to the high beam...

48. Status of the X-band 50MW klystron at BVERI

Kairong Chu (BVERI)

6/8/18, 9:25 AM

In the past 3 years, an experiment diode tube and 2 prototype tubes were manufactured at BVERI. The beam voltage of the diode tube achieves 454kV and the perveance is 0.67 μP. The first prototype is being tested, and the second is prepared to change the electron gun because sometimes its filament is partly short. With the testing of the first prototype, its frequency is mistuned from 11.402GHz...

36. Power source development activities

Gerard Mcmonagle (CERN)

6/8/18, 9:50 AM

An overview of potential consolidation and upgrades of the Xband test facilities at CERN and with collaborators, to increase the testing capability, reliability and expertise on high gradient structures.

23. High-power gyro-klystrons for acceleration applications

Dr Liang Zhang ((1)Department of Physics, SUPA, University of Strathclyde; (2)The Cockcroft Institute, Sci-Tech Daresbury, UK.)

6/8/18, 10:15 AM

High-power microwave sources play an important role in the applications of the radar system, controlled fusion plasma experiments, as well as particle accelerators. Currently, the conventional klystrons operating at S-, and X-band are the main driver in high-gradient accelerators. Klystrons with MW output power have been developed at CPI, SLAC, Thales, and so on. The most powerful klystron...
