The manipulator with helium cryostat is a versatile, closed cycle system that has many applications in ultra high vacuum research.

The manipulator can be configured with Z slide, XY stage or differentially pumped rotary feedthrough. The modular construction means that the specification can be upgraded or modified by the addition or replacement of well defined modules. The standard mounting flange is DN 100CF. The system typically includes a compressor, high pressure hoses, expander, temperature controller, heater and sensor.


▪ Full motorisation
▪ Full software control
▪ Helium recovery system
▪ Possibility to mount an angular device for PES calibration
▪ Additional electrical contacts for silicon sample direct heating
▪ Low vibration cryostat
▪ Temperature stabilisation
▪ Heating option: direct, resistive or EB

Heating and cooling methods

Sample temperature depend on sample holder type:
▪ EB heating - up to 1000 °C (second stage)
▪ Direct heating with 10 A
▪ Resistive heating (on request)
▪ Liquid helium cooling:
  - below 10 K* (5-axes manipulator)
* parameters achieved without stabilisation and without heating option.
