CSA Short Courses

As part of its goal to provide educational opportunities to professionals in cryogenics and related fields, the Cryogenic Society of America (CSA) will again offer short courses right before the Cryogenic Engineering Conference/International Cryogenic Materials Conference (CEC/ICMC). Courses will be held on Sunday, June 16, 2013, at the Anchorage Marriott Downtown, Anchorage AK.

Attendees can choose one of two full-day courses or the half-day course. These will be taught by expert instructors who possess practical knowledge of the topics they teach. Each student will receive a copy of the course notes assembled by the instructors.

Full-Day Courses: $350 early (on or before April 13), $375 regular (after April 13), $200 full-time student with ID
Half-Day Course: $200 early (on or before April 13), $210 regular (after April 13), $115 full-time student with ID

Course Descriptions:

“Introduction to Cryogenic Engineering”

Instructors: Tom Peterson (Fermi National Accelerator Laboratory) and Dr. John G. Weisend II  (European Spallation Source)

This course provides a survey of the basics of cryogenic engineering. Topics covered include the following: properties of cryogenic fluids, cryogenic properties of materials, refrigeration and liquefaction, cryostat design, helium II, cryogenic equipment, instrumentation and safety in cryogenic systems. Extensive examples are drawn from the fields of accelerator cryogenics, superconductivity and space cryogenics. There is an emphasis on providing useful data and pointers to additional resources.

“Fundamentals of Cryocoolers with Applications to 4K Systems”

Instructors: Dr. Ray Radebaugh (ret. NIST) and Dr. Chao Wang (Cryomech, Inc.)

Cryogenic temperatures provide benefits in a wide variety of applications. However, various problems usually occur in achieving such temperatures that often hinder the development of applications. Developments in cryocoolers in the past twenty years or so have alleviated many of these problems, which have ushered in many more practical applications, especially many space and superconductor applications. This course will review many of the advances that have been made to overcome some of these problems. The course will begin with a study of cryocooler fundamentals and then will show how these principles are used in the various types of gas-cycle cryocoolers to achieve temperatures from about 2K to 150K. The operating principles of the major cryocooler types will be discussed, which includes Joule-Thomson, Brayton, Claude, Stirling, Gifford McMahon and pulse tube systems.

A new area to be covered in this course explores the advances that have been made recently to allow Gifford-McMahon and pulse tube cryocoolers to reach 4K. Because helium gas prices have been increasing rapidly in the last few years, many applications that previously had used liquid helium are now switching to the use of 4K cryocoolers. Some examples of 4K systems will be given in which the transition has been easy and others where certain challenges have had to be overcome. Some solutions for the existing liquid helium cryostat will also be introduced.

“Thermodynamic Fundamentals for Cryogenics”

Instructor: Dr. Friedrich Haug (CERN)

Knowledge of thermodynamics is essential for cryogenics engineering. This course is intended to describe fundamentals in thermodynamics with an emphasis on processes and cycles. A brief introduction is given with a historical description of early liquefaction attempts of gases and the physics concepts relevant for thermodynamics are reviewed. Processes and thermodynamic cycles of large and small scale refrigerators/liquefiers including cryocoolers are described, followed by a brief discussion on the methods to reach temperatures below 2K. A chapter of the course is dedicated to the assessment of the quality of real cycles. The course is primarily designed for beginners in the cryogenics field and suited for students and engineers new to the field.
