Cryocoolers are the devices used to reach cryogenic temperatures. A cryostat is likely to be used to reach and/or maintain similar conditions or keep some environment in cryogenic stasis. Cryogenics is a branch of physics (or engineering) that studies the production of very low temperatures (below –150 °C, –238 °F or 123 K) and the behavior of materials at those temperatures. ...
A Cryogenic Processor is a unit designed to reach ultra-low temperatures (usually around -300°F / -150°C) at a slow rate in order to prevent thermal shock to the components being treated. ... Adiabatic demagnetization is a technique for attaining temperatures well below 1 kelvin. ... A dilution refrigerator is a cryogenic device first proposed by Heinz London. ...

Due to the lack of outgassing data as a function of temperature, a linear function was adopted, assuming desorption of gases from a monolayer.
Care must be taken in applying values in Table 1 for Equation 2, for the contamination level inside a cooler is a function of the amount of gas in the cooler.
"Cryocooler Contamination Study: Temperature Dependence of Outgassing", to be published in the proc.
The cooling stations of the cryocooler can be used to remove heat from the leads but the leads have to be electrically isolated from the cryocooler and one another while still having a sufficiently high thermal conductivity so that heat transferred down the leads can be intercepted before it reaches the magnet.
A flange 67 on cryocooler 71 is secured to the second flange 63 with the cold end of the cryocooler including the two cooling stages 73 and 75 extending into the inner sleeve 15.
Heat transfer between the second stage cryocooler heat station and the shield 23 directly surrounding the winding form having magnet windings 101 is accomplished by copper cylinder 21a being directly bolted to the copper shield 23.
