VUV photoemission beamline description

New manipulator

In 2015 we installed and tested a new manipulator with liquid Helium closed-cycle cryostat.

The stage (Vab Vacuum) allows linear motion along the X, Y, and Z axes and polar rotation (360°) with 0.2° accuracy.

The closed-cycle cryostat, provided by ARSCryo, works in the temperature range 9-450K. There is no He consumption (the autonomy of the compressor is 12000 hours). 

Azimuthal rotation (±160°) is performed with 0.01° accuracy through piezoelectric rotary stage (AttoCube ANR24rotary stepper positioner).
