The DC (Formerly HPD) Model 104 Olympus ADR Cryostat
Large cylindrical Pulse Tube ADR cryostat
The Danaher Cryo (formerly HPD) Model 104 Olympus is common among users needing large experimental volumes.
Model 104 Olympus Deep Dive
The Model 104 Olympus uses a two-stage ADR to reach temperatures as low as 30 mK. An ADR operates by subjecting a salt crystal to strong magnetic fields. In these different states, the salt crystal will either absorb or dump thermal energy. This is used to shuttle heat away from the sample stage achieving mK temperatures. Because of the nature of this process, only a certain amount of heat can be absorbed before the crystal must be warmed up and regenerated.
Designed with customization in mind, the Model 104 Olympus is fitted with two large electrical breadboards at both 4 K and 50 K. Additionally, there are multiple customizable feedthroughs in each stage plate. If you are constrained by cooldown times, the Model 104 Olympus can support Rapid Cool liquid nitrogen heat exchangers. It is a robust “turn-key” mK alternative to dilution refrigerators.
Applications: Astronomy, Spin QC, Photonic QC, Material Characterization, Condensed Matter Physics

Accessory Add-Ons
Custom Service Stand
The top plate of the cryostat has mounting provisions that allow the cryostat to be attached to the service stand (same service stand as 106 and 107?). This mount consists of a plate and ball attached to rods extending from the top plate of the vacuum jacket. The Service Stand attaches to the ball for lifting. Three jack screws on the top plate of the Service Stand allow for tilt adjustment and for locking the cryostat. The ball allows for rotating, and some slight swinging, of the cryostat. The service stand has casters to allow it to be rolled into position for attaching the cryostat.
The Service Stand has a vertical height adjustment capability that allows for placing the cryostat on a bench or other support structure. The vertical travel is approximately 76 cm.
