by Dr. Ray Radebaugh, NIST Fellow Emeritus | 8:00AM – 5:00PM
Many systems benefit by operating at cryogenic temperatur es, such as increased fluid densities, appearance of superconductivity, and reduced thermal noise in low-level signals. Such benefits may require temp eratures in the range of 10 mK to 150 K, depending on the application. Cryo coolers are used in most cases outside the laboratory to achieve such tempe ratures. However, the use of cryocoolers can present some disadvantages tha t can hinder the development of applications. Most cryocooler R&D effor ts are undertaken to alleviate many of these disadvantages, which have ushe red in many more practical applications, especially many space and supercon ductor applications. This course will review many of the advances that have been made to overcome some of these disadvantages, and then proceed to dis cuss new areas of research. The course begins with a discussion of the many different types of applications and market size. Cryocooler fundamentals, such as thermodynamics and heat transfer are then introduced to help unders tand the operating principles of the various gas-cycle cryocoolers used to achieve temperatures from about 2 K to 150 K. These cryocoolers include Jou le-Thomson, Brayton, Claude, Stirling, Gifford McMahon, and pulse tube syst ems. The advantages and disadvantages of each type will be discussed, and e xamples of each will be shown. Millikelvin cooling technologies that can be combined with cryocoolers for cryogen-free operation at sub-kelvin tempera tures are also briefly described. Design principles and the major software packages of REGEN3.3, DeltaEC, and Sage will be explained and compared with CFD modeling. A brief section on construction techniques and measurement m ethods is also included to assist in hardware development.
Dr. Ray Radebaugh is a NIST Fellow Emeritus with the Applied Chemicals and Mate rials Division. He joined NIST in 1966 as a post doc for the first two yea rs and stayed on in a permanent position since then. He was the leader of the Cryogenic Technologies Group from 1995 until his retirement in 2009. H is research focused on cryogenic refrigeration and material properties. He has taught short courses on cryocoolers since 1981.

Cryostats are a fundamental
building block of cryogenic systems and successful design and construction
of these devices is vital for project success. This half day course will co
ver some of the most important aspects of cryostat design. It will illustra
te these aspects via examples of real-world cryostats including those from
ESS, ILC, LHC and laboratory cryostats. Best practices and references for a
dditional reading will be provided. Topics to be covered include:
1. D
efinition of Requirements
2. Cryostat Materials
3. Thermal Insula
tion
4. Structural Design
5. Safety Considerations
6. Instru
mentation

by Dr. Jacob Leachman, Associate Pr ofessor, Washington State University and Dr. Konstantin Matveev, Professor, Washington State University | 8:00AM – 12:00PM
Interest in liqu id hydrogen is increasing at an unprecedented rate around the globe. Howeve r, the cryogenic and flammable nature of liquid hydrogen fuel adds consider able difficulty for even seasoned experimentalists. This introductory cours e will cover the basics of project startup with liquefied hydrogen includin g fluid specific information on: 1) Thermophysical properties, 2) Liquefact ion and Storage, and 3) Safety Standards and Applications. Participants wil l leave having completed basic calculations on thermophysical properties, e xamples for constructing cryogenic test equipment, and processes for develo ping safety plans. The course accompanies a textbook under the same name th at is under development by the instructors.
Konstantin Matveev is a profess
or in the School of Mechanical and Materials Engineering at Washington Stat
e University and a fellow of the American Society of Mechanical Engineers.
His PhD work at Caltech resulted in reduced-order models and experimental s
etups for thermoacoustic instabilities in resonators. Dr. Matveev carried o
ut post-doctoral research at Los Alamos National Laboratory on nonlinear th
ermofluid phenomena with applications to thermoacoustic engines and refrige
rators. At Washington State University, he explored miniature thermoacousti
c prime movers and coolers and conducted computational modeling of heat-sou
nd interactions in porous media. In recent years, Dr. Matveev extended his
work to low-temperature systems, carrying out research on cryogenic hydroge
n storage and cooling, non-equilibrium multi-phase cryogenic flows, acousti
c oscillations in cryogenic environment, and para-orthohydrogen conversion.

artment of Defense, Department of Energy, and industry.
by Dr. A.T.A.M. (Fons) de Waele, Retire d, Eindhoven University of Technology | 1:00PM – 5:00PM
In this Short Course, the thermodynamics (basic principles, osmotic enthalpy, cooli ng power, heat exchange, limitations, etc.) and hydrodynamics (superfluid h ydrodynamics, two-component hydrodynamics, etc.) of dilution refrigerators (DRs) will be introduced. Variants such as wet, adsorption, and space DR’s will be treated. Dry DRs will be discussed in relation to the present inter est in DRs as they provide the low-temperature environment for quantum comp uters.
De
Waele got his PhD in Leiden in Dec. 1972 on the Josephson Effect. Afterward
s he moved to the Eindhoven University of Technology where he stayed for th
e rest of his career. From 1973 to 1994 he worked on dilution refrigeration
. In 1995 he changed topics and started working mainly on pulse-tube refrig
erators until his retirement in 2001. He had 18 PhD’s under his supervision
. De Waele was active in teaching thermodynamics, mechanics, and cryogenics
for the students in Eindhoven, but he was also organizer of cryo courses f
or PhD students and has given short courses on DR’s and cryocoolers in many
places all over the world. In retirement, De Waele is still active as an a
dvisor in various projects.
by Dr. Scott Courts, Senior Scientist, Lake Shore Cryotronics | 1 :00PM – 5:00PM
Temperature is likely the physical parameter most often measured even though it’s rarely the main physical parameter of inte rest. Proper installation and operation of any type of sensor at cryogenic temperatures is challenging, but especially so for temperature sensors. The temperature measurement is complicated by a number of factors including th ermal connection between the sensor and experiment, limitations on excitati on power, heat leak to the sensor, distance from sensor to instrument, and noise. The effects of any of these can be indistinguishable from a true var iation in temperature. This short course is designed to provide an introduc tion to cryogenic temperature sensors and associated reading electronics to temperatures down to 10 mK. The course gives a basic overview of
• T
emperature sensors and their properties
• Selection criteria for appli
cations and the tradeoffs involved
• Proper installation techniques fo
r the sensors
• Selection criteria for the instrument
• Proper op
eration of the sensor / instrument combination
• Suggestions for optim
izing the performance
• Troubleshooting when problems arise.
Emp hasis is placed on the practical aspects of performing accurate temperature measurements.
