Description
To reduce the thermal background or the noise in the detectors, scientific instruments frequently need to be operated at cryogenic conditions at or below 80 K. The combination of low temperature and vacuum creates an environment, which is very different from the typically lab environment and thus mandates a different approach in the design of the mechanics, optics and mechanisms. This talk will give an introduction to the physics of cryogenics and present the technologies and techniques required to develop instruments operating at these conditions.
