Head
EBT-100 power supply
Remote controller(EBR-100)
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.
Features
- 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
Applications
- The tip of the electron beam STM probe is heated and cleaned In ultra high vacuum
