M. Breidenbach et al., AN INVERTED-GEOMETRY, HIGH-VOLTAGE POLARIZED ELECTRON-GUN WITH UHV LOAD LOCK, Nuclear instruments & methods in physics research. Section A, Accelerators, spectrometers, detectors and associated equipment, 350(1-2), 1994, pp. 1-7
The design of a high voltage electron source with a GaAs photocathode
and a load lock system is described. The inverted high voltage structu
re of the gun permits a compact and simple design. Test results demons
trate that the load lock system provides a reliable way to achieve hig
h quantum efficiency of the photocathode in a high voltage device.
