FRA-2X1-2 - EGPS-1011 ELECTRON GUN
Description
The Kimball Physics FRA-2X1-2 Electron Gun, with its matching EGPS-1011 Power Supply, is intended for use in a variety of UHV, surface physics, charge neutralization, and processing applications. It is a complete subsystem ready to attach to the user’s vacuum system and turn on. Both beam energy and beam current are adjustable over wide ranges. The FRA-2X1-2 Electron Gun uses a refractory metal cathode to generate a uniform flood beam. The cathode was specifically designed for low energy spread. The gun design allows for generation of the beam down to low energies, and very low currents. The FRA-2X1-2 can produce modest beam currents at energies as low as 5 eV. It can deliver maximum beam currents of 50 μA at 5 eV, and 400 μA at 1000 eV. The FRA-2X1-2 low-energy electron flood gun uses a planar triode design. An acceleration grid enhances beam current at low energies. Secondary electrons which may be generated at this grid cannot exit the electron gun because of the positive potential (0 to +100 V with respect to the cathode) applied to the grid. Enhanced in design for flood gun performance at low energies, the FRA-2X1-2 Electron Gun has a half angle divergence at 50 eV of 11.5 degrees. As the beam energy is increased, the divergence decreases. Larger spots are achievable at low energies, but not necessarily at higher energies.
