The Entropy cryostat with Joule-Thomson stage offers continuous operation at temperatures around 1K and a cooling power of a few Milliwatt.
Entropy JT cryostats are available as M- and L-series based on pulse-tube coolers with a cooling power of 0.5W or 1.0W at 4.2K and various sample space.
JT stage with turbo pump:
- Base temperature: < 0.9K
- Cooling power: a few mW at 1.0K
JT stage with fore pump only:
- Base temperature: < 1.2K
- Cooling power: a few mW at 1.3K
Sample space at 4K:
- Ø 230 x 300mm (M-series)
- Ø 300 x 300mm (L-series)
- Or completely custom-made
Application example:
Cryostat for operating 64 Superconducting Single Photon Detectors (SSPDs) below 1K.
The systems come fully featured up with temperature sensors, heaters, electronics and software with TCP/IP interface for remote control.
Several accessories such as DC cables, coax cables, circuit boards, fibers, optical ports and sample magnets are available on request.
