Instrumentation and Control of Large Helium Cryogenic Systems

New Content Item

Automated control of large Helium Cryogenic Systems is vital to the reliable operation of the large scale scientific devices such as particle accelerators and fusion experiments that require liquid helium temperatures. The proper design and implementation of these control systems is a significant part of the cryogenic system and can represent a major cost, schedule and performance risk. This issue reviews the design and operating experience of the control systems from a number of existing cryogenic systems and also discusses the control approach to a number of cryogenic systems under development. Topics such as hardware and software choices, links to larger control systems, use of community standards and resulting performance are covered.

Topics of interest include but are not limited to theoretical aspects, algorithms, methods, and fields of applications, as:

•    Helium Refrigeration Plants
•    Automation, Controls Software
•    EPICS
•    Integration with Large Scientific Facilities
•    Particle Accelerators
•    Fusion Devices
