Adiabatic Demagnetisation Refrigerators (ADR) and Dilution Refrigerators (DR)
from High Precision Devices (HPD)
HPD offers a large variety of cryostats which can be configured individually. Depending on the required temperature and cooling power, different combinations of cryostats like pulse tube, ADR or dilution refrigerator may be chosen. Various contacting options like electrical feedthroughs, microwave conductors or fibers can be integrated.
Superconducting magnets can also be integrated.
For research in the millikelvin range, ADRs are a cost-effective alternative to DRs.
|30 mK – 300 K temperature range|
|Closed helium cycle|
|Multiple cooling stages may be used for different experiments|
|Up to Ø 44 cm x 60 cm height|
Cryostats from HPD are flexible and individual solutions developed together with our customers. Different combinations of cooler types can be selected depending on the required base temperature and cooling power.
Multiple experiments can be simultaneously installed at different temperature stages of the cryostat.
Astrophysics requires very sensitive detectors with high band widths. A bolometer provides these properties. To suppress noise and maximize its sensitivity, the bolometer is cooled down to the millikelvin range.
Quantum transport phenomena are target of a strongly growing field of research. As the stability of a quantum system dramatically increases at low temperatures, most setups use a cryostat to cool the system to a few kelvin or millikelvin.
Semiconductor experiments like single electron tunneling or quantum dot measurements require very low temperatures.
Low-Tc superconductors or SQUID sensors are popular examples of applications which require cryostats for low temperatures.
„We use the Model 103 ADR cryostat for our microwave kinetic inductor detectors (MKID) research. An important feature for us is the quick turn-around time and simple operation, as well as the large sample space. We also appreciate the reliability of the system and compliance with the performance specifications.”
