Introduction
Cryostats are the fundamental building blocks of cryogenic systems. Their basic function is to keep equipment and materials at the desired cryogenic temperature. Cryostats may contain a wide variety of equipment, for example: superconducting magnets, telescopes, detector arrays, beam targets and material test assemblies. In addition, many cryostats have unique requirements; such as the need for particle beam or optical access, severe alignment or vibration tolerances, extremely low heat leak or the capability for space launch.
Despite this variation, all cryostats have common design issues and solutions. It is the goal of this short course to survey the fundamental aspects of cryostat design and illustrate solutions by using existing designs. The class will include practical design techniques and data as well as references to more detailed information. Students, new cryostat designers and researchers that use cryostats in their work will all benefit from this class.
