Subject: UCLA short courses on Cryogenics

Two short courses on cryogenics.

On February 24-28, 1997, UCLA Extension will present the short course,
"Advanced Long-Life Cryocoolers", on the UCLA campus in Los Angeles.

The instructors are Ray Radebaugh, PhD, NIST; Graham Walker, PhD,
University of Calgary; Robert Fagaly, PhD, Conductus; Gerald Pruitt,
Hughes Electron Dynamics; and Ron Ross, JPL.

Each participant receives extensive course notes and the text,
"Low-Capacity Cryogenic Refrigerators",  G. Walker and E.R. Bingham
(Oxford University Press, 1994).

This course provides a thorough introduction to cryocoolers (miniature
refrigerators used to achieve and maintain cryogenic temperatures of less
than 120K).  It deals with both regenerative and recuperative cryocoolers,
with emphasis on such regenerative systems as the Stirling, Vuilleumier,
Gifford-McMahon, and pulse tube.  Recuperative systems include the
Joule-Thomson, Brayton, and Claude cycle. Instruction focuses on smalland
intermediate capacity cryocoolers designed for infrared detectors,electronic
devices, superconducting sensors, superconducting magnets,and cryopumps.  This
course does not cover large-scale industrialliquefaction turbine systems.

Fundamentals and operating principles of the mechanical regenerative
devices most often used for the 65-80K temperature range are explained,
especially in the context of the new high-temperature superconductors.
Multistage devices which achieve much lower temperatures are then
discussed.  Design methods as well as construction techniques are
covered in detail.  The latter part of the course deals with small and
intermediate recuperative systems, and addresses various alternative
non mechanical systems for temperatures ranging from 120K down to the
nanokelvin range.  Magnetic refrigerators are also analyzed in this segment
of the course.  Such application areas as infrared detectors,
superconducting quantum interference devices (SQUIDs), superconducting
magnets, maser and parametric amplifiers, computers, and high-temperature
superconductors are examined, with an emphasis on interfacing problems.

Two site visits are a highlight of the course.  The first is to UCLA Professor
T.H.K. Frederking's laboratory where research on cryogenic heat transfer
and pulse tube refrigeration is being conducted.  The second is to the Jet
Propulsion Laboratory in Pasadena, a major research and development
lab for unmanned spacecraft and a leader in cryocooler R&D.

UCLA Extension has presented this highly successful short course since
1980.

The course fee is $1595, which includes the text and all course materials.
These materials are for participants only, and are not for sale.

On March 3-4, 1997, UCLA Extension will present the short course,
"Cryogenic and Hydrogen Safety", on the UCLA campus in Los Angeles.

The instructors are Frederick J. Edeskuty, PhD, Los Alamos National
Laboratory; and Mark A. Daugherty, PhD, Los Alamos National Laboratory.

Each participant receives extensive course notes and the text, "Safety in
the Handling of Cryogenic Fluids", F.J. Edeskuty and W.F. Stewart (Plenum
Press 1996).

Safety for workers and/or the public is a vital consideration for any
industrial
or laboratory operation. The cost of accidents is another factor to consider,
and where cryogenic systems are involved, equipment replacement costs
can be substantial compared to other systems.

This two-day course is intended for scientists, engineers, and technicians
involved in programs that make use of cryogenic fluids in any capacity, or in
the utilization of hydrogen as a fuel. The course should enable participants
to recognize the causes for potential hazards and methods to eliminate
them. Lectures are arranged so that the safe handling of cryogenic fluids
and the hazards of hydrogen as a cryogen are discussed on the first day.
The second day also addresses cryogenic fluids, but focuses on the
specific problems of handling hydrogen, either as a liquid or as a gas at
ambient temperature.

The course fee is $895, which includes the text and all course materials.
These materials are for participants only, and are not for sale.
