ELG-2 - EGPS-1022 ELECTRON GUN
OVERVIEW
The Kimball Physics ELG-2 Electron Gun, with its matching EGPS-1022 Power Supply, is intended for use in electron stimulated desorption studies, secondary electron emission coefficient measurement studies, surface physics and other vacuum physics studies. It is a complete subsystem ready to attach and turn on. Beam energy, beam current and spot size are independently adjustable over wide ranges. The energy is variable from 1 eV to 2000 eV, with a low range included for improved resolution at the lowest energies. By use of multistaging and a computer-designed electron zoom lens, a constant beam current is maintained over a twoorder-of-magnitude change in energy, with a spot size also roughly constant. The gun can deliver 1 μA into an approximately 1 mm spot, at a 2 cm working distance and 10 eV. The electron gun uses a unipotential refractory cathode to generate a beam of low energy spread. UHV technology is used throughout. The gun can be run in vacuums from 10-11 torr up to 10-5 torr for the standard Ta disc cathode. The electron gun is bakable to 350°C with cables removed.
