4-6 Axis Helium Manipulators (Open Cycle)

The manipulator is a high precision, high rigidity, UHV specimen manipulator of modular construction, suitable for a range of X, Y and Z linear motions and R1, R2 and R3 rotations.

The modular construction means that the specification can be upgraded or modified by the addition to replacement of well defined modules.


▪ Full motorization
▪ Full software control
▪ Helium recovery system
▪ Possibility to mount an angular device for PES calibration
▪ Temperature stabilization
▪ Heating option: direct, resistive or EB

Heating and cooling methods

Sample temperature depend on sample holder type:
▪ Direct heating with 10 A
▪ Resistive heating up to 1100 °C
▪ EB heating up to 1400 °C
▪ Liquid helium cooling:
- 4 axis manipulator - down to 4 K*
- 5 axis manipulator - down to 4.8 K* / 10 K**
- 6 axis manipulator - down to 7 K* / 15 K**
* parameters achieved without heating option and temp. stabilization.
** parameters achieved with heating option.
