Tip cleaning by electron beam heating in UHV conditions

Electron-beam Heater for STM tip EBT-100 Head EBT-100 power supply Remote controller

Compact electron beam gun and power supply for STM tip cleaning in UHV. Thermal electrons from a tungsten filament are focused on the STM tip. Tip filament distance is able to adjust by linear motion feedthrough.


  • Easy operation, light weight, compact
  • Intensive heating of probe tip in ultra high vacuum
  • Dramatic effect on data improvement in Ultra-high vacuum STM measurement


  • The tip of the electron beam STM probe is heated and cleaned In ultra high vacuum
