DRY ICE 1K ARPES
The DRY ICE 1K ARPES is a closed-cycle, side-loading system that has been specifically designed for Angle Resolved Photoemission Spectroscopy (ARPES) research in UHV conditions.
The system has a maximum of 6 axes of precise sample movement and rotation using both automated and manual drives. The design incorporates two 1K pots for improved cooling power direct to the sample, allowing a cooling power of 100mW at 1.6K.

The Shanghai Synchotron facility operates a High Cooling Power 1.7K cryostat with 200mW of cooling power to overcome the heat-loads generated by the ARPES beamline.
This customised system was designed to be UHV compatible and with 4 or 6 axis of UHV manipulation whilst maintaining a low precession movement of <0.5mm off-axis during manipulation. The sample is mounted on a modified standard sample holder to allow sample exchange by raising the insert up into the sample exchange position using UHV bellow and manipulators. The system provided the highest cooling power @ sub 2K available in a commercial DRY ARPES cryostat
