About the VA-935A
The VA-935A is a klystron manufactured by CPI (formerly Varian). High-power S-band klystron at 2.856 GHz delivering 5 MW peak output for medical and physics linear particle accelerators.
Key ratings of the VA-935A include tube type Klystron, frequency 2.856 GHz, frequency band S-band, mode Pulsed, peak output power 5 MW and average power 5 kW.
Typical applications are medical linear accelerators, physics particle accelerators, free-electron lasers and synchrotron injector linacs. Notable features: 5 MW S-band peak output, medical accelerator standard, 55 dB high gain and precision frequency control.
Klystrons are linear-beam microwave amplifiers delivering high gain and high peak power. They power particle accelerators, medical linacs, radar transmitters and satellite uplinks, and are usually driven by a high-voltage pulse modulator switched by a thyratron.
