Kimball Physics Electron Gun (Beam) Systems typically include a matching power supply to provide a complete subsystem that is ready to attach to the user’s vacuum hardware and turn on.
Beam energy, beam current and spot size on many systems are independently adjustable over their wide ranges and can be controlled with an optional LabviewTM computer interface.
Most of our systems are UHV (ultra-high vacuum) compatible in vacuum conditions up 10-11 torr. Depending on the system, various cathodes options are available and include:
-
- Barium Oxide discs (BaO, low light, low energy spread, min. vacuum 1×10-7 torr)
- Yttria-coated Iridium discs (Y2O3 Iridium, rugged, vacuum up to 10-4 torr, may survive brief loss of vacuum)
- Tantalum disc cathodes
- Single-crystal Lanthanum Hexaboride (LaB6, small spot, high brightness, min. vacuum 1×10-7 torr)
Kimball Physics products have evolved into a broad range of electron beam systems that we arbitrarily characterized as low energy (up to 5 keV), medium (up to 30 keV) and high (up to 100 keV) energy systems. Many of the systems were born from custom projects, which still is a large portion of our focus.
High Energy Systems, with energy ranges from 1 keV up to 100 keV, currents ranging from 1 nA to 2 mA, and spot sizes from 50 micron to 500 mm are available.
The tables below provide comparison of the Electron Gun System specifications and the typical Applications and Features for each High Energy Electron Gun System.
