DOE Approval Moves PIP-II Accelerator Upgrade To Perform Baseline Stage at Fermilab
The US Department of Energy formally approved Fermi National Accelerator Laboratory (CSA-CSM) to proceed with its design of PIP-II, an accelerator upgrade project that will provide increased beam power to generate an unprecedented stream of neutrinos—subatomic particles that could unlock our understanding of the universe—and enable a broad program of...
In Memoriam: Dr. Roger W. Boom
It is with great regret that we report the death of Dr. Roger W. Boom, emeritus professor from the University of Wisconsin and mentor and inspiration to a great many leaders in the fields of cryogenic engineering and superconductivity. Dr. Boom’s career spanned more than thirty years during which he...
New Study Calls for US-based Electron Ion Collider
A new report, sponsored by the DOE and undertaken by the National Academies of Sciences, Engineering and Medicine, argues that a domestic electron ion collider could unlock the scientific mysteries of atomic nuclei and maintain US leadership in accelerator science.
Hawaiian Researchers Choose Cryogen-free MRI to Study Kidney Disease
MR Solutions has installed a cryocooler-based, and thus cryogen-free, preclinical MRI imaging system at the University of Hawaii to help researchers improve the rate of kidney disease detection. One in seven residents on the island has chronic kidney disease, a figure far higher than normal among its residents of Japanese,...
Health Officials in NY County Ban Liquid Nitrogen Treats
The Clinton County Board of Health has banned the sale of food products adulterated by liquid nitrogen. The move followed a study of Dragon's Breath, a dessert composed of cereal puffs frozen with liquid nitrogen, discussed on a New York State Association of County Health Officials conference call.

Space Cryogenics
Space cryogenics is, somewhat obviously, the application of cryogenics to space exploration and science. The use of cryogenics in space optimizes the launching of vehicles, provides power and life support to spacecraft and is critical for many scientific observations.Space cryogenics has a number of challenges and has driven both pure...
Exergy
The science of thermodynamics plays a major role in cryogenics. It underlies the various refrigeration cycles, from Carnot to Brayton (Cold Facts Vol. 32 No. 2) and Joule-Thomson, is a fundamental part of the definition of terms such as coefficient of performance (Cold Facts Vol. 31 No. 1) and even...
Cryogenic Treatment
Cryogenic treatment is the process of cooling materials to cryogenic temperatures temporarily to improve their material properties at room temperature. This is distinct from cooling materials down to cryogenic temperatures to take advantage of phenomena such as superconductivity that only occur at cryogenic temperatures. Cryogenic treatment, sometimes also referred to...

You are encouraged to read Cryo Central’s History...
Bose-Einstein Condensate
A Bose-Einstein condensate, first proposed in 1925 by Albert Einstein based on work done by Satyendra Nath Bose (the same Bose from whom the term boson is derived), is a super-cold state of matter in which almost all of the individual atoms have “condensed” down to the lowest possible quantum...
Cold Technology for Pest Control
While it does not reach temperatures cold enough to be called cryogenic, carbon dioxide snow is at the heart of a new way of dealing with unwanted pests. It utilizes a quick freezing process that takes advantage of the properties of carbon dioxide snow and has a number of benefits...
Cryogenic Finishing
The following 3 articles discuss the uses and procedures of various type of cryogenic finishing. 1) By Robin A. Rhodes, Cryogenic Institute of New England, Inc. rrhodes@nitrofreeze.com Cryogenic Deflashing is employed to remove undesired residual mold flash that remains on molded parts after they are removed or ejected from the...
Thermal shock on steel cylinder when dropped into liquid nitrogen
We are a research team at the University of South Florida, studying the “thermal shock” on a steel cylinder when it is dropped into liquid nitrogen. We want to make sure that the thermocouple does not get influenced by the surrounding LN2. Any advice?
Getter materials to absorb out gassed materials?
Here’s one for the scientists: We would like to sell vacuum insulated pipe for high temperature fluid applications. Are there any good getter materials that we can place in the vacuum space of our VJP to absorb outgassed materials at elevated temperatures?
Data on Carbon Fibres Reinforced Plastic at temperatures between 4 and 300K.
I am looking for data on Carbon Fibres Reinforced Plastic at temperatures between 4 and 300K. I would appreciate it if someone could give me some hints on where to find it.
