The *Cryogenic Society of America *(CSA) is offering two Full Day Short Courses and one Half Day Short Course on Monday, June 13, 2011, at the Spokane Convention Center.

Safety in Cryogenic Systems
by Dr. Friedrich Haug (CERN), Tom Peterson (Fermilab) and Dr. John Weisend II (FRIB/MSU)

Knowledge of safety in cryogenics is vital for personnel handling cryogens and for the engineer and technician designing and constructing cryogenic equipment and systems. The properties of cryogenic fluids and of materials at cryogenic temperatures create unique hazards. This course covers a variety of topics and is suitable for students and professionals working in all areas of cryogenics including large and small scale systems.

New! Fundamentals of Cryocoolers with Applications to 4K Systems
by Dr. Ray Radebaugh (ret. NIST) and Dr. Chao Wang (Cryomech, Inc.)

The course begins with a study of cryocooler fundamentals and then shows how these principles are used in the various types of gas-cycle cryocoolers to achieve temperatures from about 2K to 150K. 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.

Cryogenic Temperature Sensors and Instrumentation
by Dr. Scott Courts (Lake Shore Cryotronics, Inc.)

The course gives a basic overview of various types of instrumentation, selection criteria, proper operation and optimizing their performance. Emphasis is placed on the practical aspects of performing accurate temperature measurements.
