The figure below represents a schematic of the HelioxVT running in a VTI. The HelioxVT insert can be treated like any sample rod for a variable temperature insert. Once loaded, the insert is cooled by the VTI from 300 K down around 10 K using exchange gas. The 3He gas contained in a small dump sitting on top of the insert is then condensed at around 1.5 K. Once the 3He pot has reached a stable temperature and condensation is completed, the adsorption pump will start to cool the 3He pot and experimental set-up to below 300 mK. The condensation and the cool down time typically require less than 1 hour.
