The model HE-3-SSUHV-SPM/ESR cryostat is designed for versatile applications with sample in UHV environment.
HE-3-SSUHV-SPM/ESR Cryostat for Scanning Probe Microscopy and Electron Spin Resonance Mechanical Drawing
The system contains two identical He-3 inserts which provide very large cooling power for various types of experiments. A "universal" sample mount made of gold plated OFHC copper is thermally connected to the two He-3 pots. This is used for cooling Scanning Probe Microscope heads, Electron Spin Resonance devices and a variety of other experiments.
A high field superconducting magnet as well as an ESR modulation coil are supplied with the system. The ESR modulation coil can reach a field of 1350 gauss, with a 27 gauss per ampere resolution.
A clear shot access, with a 4.2 K thermal anchor stage, is incorporated into the system so that the cryostat can be turned into a top-loading system with minor modifications.
This He-3 cryostat includes the following main components:
- Thermometer and heater on the sample mount
- Charcoal sorption pumps with heaters and thermometers
- 1 K pot with thermometers
- 1 K cold plate for wiring thermal anchor
- He-3 pot with heaters and thermometers
- UHV as well as standard vacuum cans
- Gas handling system
- Operation test
