Description
The EMG-4193 Electron Gun with matching EGPS-4190 Power Supply and COPS-4190 Column Optics unit is a complete subsystem ready to attach to the user’s vacuum system. Optional photo emission may be achieved by focusing a user supplied electromagnetic radiation source through the system’s unique viewport. The EMG-4193 can deliver electrons with energy from 1 keV to 30 keV and current from 1 nA to 10 µA. The gun uses an (LaB6) cathode to provide a small spot down to 25 µm with a lifetime of thousands of hours. The beam can also be rastered for imaging of the target. Applications include surface physics and vacuum physics experiments.
