Abstract:

This talk will give a brief introduction to the science/engineering of cryogenics.

The applications of cryogenics and cryogenic fluids are many, this talk will focus

mostly on cryogenic systems and applications at Jefferson Lab. Some of the critical

design/engineering considerations will be reviewed. Several components of JLab's

cryogenic systems will be highlighted including cryogenic targets, cryogenic

distribution, and a high level overview of the many portions of the laboratories

many cryogenic systems. Gas and liquid storage systems will be discussed as well as

the refrigerators/liquefies that convert the gas to liquid. Key operational processes

including helium purification will be discussed as well as process control that allows

the systems to run 24/7 without continuous staffing. At the end the attendee should

have a better feel for the scope of the JLab cryogenics system and cost and effort to

operate the systems here at JLab.
