Electron Gun Systems

Kimball Physics is a key supplier of electron guns designed for use in a wide variety of ultra high vacuum (UHV) surface physics, space physics, and processing applications. Guns can be focusable for small spot size, for use in applications such as x-ray production, welding and RHEED; or for flood beams, for use in charge neutralization, electron beam scrubbing, space simulation and radiation damage studies.

Range of Operation

  • Energy Ranges: 1 eV to 100 keV
  • Beam Current Ranges: 1 nA to 20 mA
  • Spot Size Ranges: 15 μm (focused column) to 500+ mm (flood beams)

Performance

  • Beam Current Stability: feedback-stabilized emission current control; better than ± 0.1% per hour
  • Energy Stability:  ± 0.01% per hour, ± 0.02% per 8 hours at full output to minimize chromatic aberration

Convenience

  • Customer-replaceable firing units
  • Mechanical alignment during full operation
  • Storable control settings
  • Computer remote control / metering

Operational Capabilities

  • Fast pulsing / Beam blanking
  • Deflection / Rastering
  • Gun-mounted Faraday cups
