Compact pulsed electron beam system for microwave generation

Pulsed Electron-Beam Heating

A pulsed, 20 kv electron beam is focussed upon a vapor-deposited thermocouple, and the resulting temperature vs. time response is studied. The experimental data show much scatter, but are consistent with the theoretical prediction that the characteristic thermal response time T is proportional to d , where d is the beam diameter at the thermocouple. From these data, for the soft-glass substrate...

Electron Beam Generation in Tevatron Electron Lenses

New type of high perveance electron guns with convex cathode has been developed. Three guns described in this article are built to provide transverse electron current density distributions needed for Electron Lenses for beam-beam compensation in the Tevatron collider. The current distribution can be controlled either by the gun geometry or by voltage on a special control electrode located near ...

A Control System of a Scanning Electron Pulsed Beam for an Industrial Linac

This paper describes a method and a control system of a scanning electron and a bremsstrahlung pulsed beam for industrial linac. The system uses ultrasonic emission generated by the beam in thin rods and plates, as a source of primary information about the current characteristics of each electron/bremsstrahlung pulse. The results of the uniform radiation field forming are discussed.

A Reflex Electron Beam Discharge as a Plasma Source for Electron Beam Generation

A reflex electron beam glow discharge has been used as a plasma source for the generation of broad-area electron beams. An electron current of 120 A ( 12 A/cm2) was extracted from the plasma in 10 ps pulses and accelerated to energies greater than 1 keV in the gap between two grids. The scaling of the scheme for the generation of multikiloamp high-energy electron beams is discussed. E HAVE demo...
