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.
