At the heart of NASA’s deep-space laser communication system sits a Danaher Cryogenics Model 106 cryostat, housed inside Caltech’s Palomar Observatory. It maintains a detector array at just 1 Kelvin — cold enough to achieve superconductivity — allowing it to capture the faint photons arriving from NASA’s Psyche spacecraft hundreds of millions of miles away.
Danaher Cryogenics, a leader in manufacturing of fully-integrated, sub-Kelvin cryostats and engineering elegant cryogenic solutions, today announced the acquisition of the Adiabatic Demagnetization Refrigerator (ADR) Cryogenic product line from Boulder-based High Precision Devices, Inc. (HPD), a subsidiary of FormFactor.

These advances are pursuing better measurements of the polarization and amplitude of the cosmic microwave background (CMB) radiation. These improved measurements can lead to a more complete understanding of aspects of the universe such as neutrino physics, inflation and gravitational waves, to name just a few.
In this Cold Facts article, Charlie Danaher discusses how to effectively use an ADR cryostat and what to consider when using an ADR cryostat.
Experimentalists seeking cryogenic platforms below 250 mK have essentially two choices: a Dilution Refrigeration (DR) cryostat or Adiabatic Demagnetization Refrigeration (ADR) cryostat. There are particular applications where one or the other is the best tool. In some cases, either may be equally suitable. Let’s discuss the differences.
