چکیده

For the generation of picosecond (< 100 ps) electron beam pulses, we studied the RF modulation of a conventional triode electron gun. The feasibility study for this scheme has been experimentally investigated by modulating a triode gun of the Y-824 cathode-grid (KG) structure provided by the CPI Eimac, with 2.856-GHz pulsed RF’s generated by a solid-state amplifier (SSA). In this paper, we present the methods and results of this investigation.

EXPERIMENTAL OPERATION OF A 17 GHz PHOTOCATHODE RF GUN

Initial operation of a 17 GHz RF photocathode electron gun has been achieved at MIT. This is the first photocathode electron gun to operate at a frequency above 2.856 GHz. Such electron guns have the potential for achieving record high values of electron beam quality. The 1.5 cell, p-mode, copper cavity was tested with 5-10 MW, 100 ns, 17.145 GHz pulses from a klystron amplifier built by Haimso...

Experimental and Theoretical Investigations of a 17 GHz RF Gun

We report on experimental and theoretical investigations of a 17 GHz RF photocathode electron gun. This is the first photocathode electron gun to operate at a frequency above 2.856 GHz. The 1.5 cell, π−mode, copper cavity was tested with 50 ns pulses from a 17.150 GHz klystron amplifier built by Haimson Research Corp. A Bragg filter was used at the RF gun to reduce the reflection of parasitic m...

Gyrotron for ITER

Recent megawatt gyrotron experiments at MIT have achieved record powers at 170 GHz. Single mode emission with a peak output power of 1.5 MW and an efficiency of 35% has been measured. The experiment is based on a resonant TE28 ,8 ,1 cylindrical cavity situated in a 6.7 T magnetic field. Microwaves are generated in the cavity by an 83 kV annular electron beam produced by a triode-type magnetron ...

Photoelectron beams from the UCLA rf gun

A high brightness, low emittance photocathode rf gun is starting operation at UCLA as an injector to a 20 MeV linac. This linac will initially be used to drive FELs, plasma wakefield accelerators, and to test plasma lenses. The gun is a 1 89 cell ~r-mode standing wave structure running at 2.856 GHz, and has a copper photocathode. In the initial commissioning of the gun, photoelectron beams of u...
