NASA Goddard Hosts Young Women for STEM Girls Night In
Late on a Friday night, 40 high school girls arrived at NASA’s Goddard Space Flight Center in Greenbelt MD for a STEM-themed sleepover, ready to learn about careers in science, technology, engineering and math.
Dr. Roger W. Boom 1923-2018
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.
Cryogenics in Medicine and Biology
The field of cryogenics has been connected with medical applications since its inception, and what follows is a historical review of some of the major applications within medicine where the term cryogenic is used in a specific manner.
DH Industries Contributes To Successful Launch of LNG Barge
The successful completion and delivery of Clean Jacksonville was announced in August, including information on the involvement of CSA member DH Industries BV.
Towards Cryogen-Free SRF Particle Accelerators
Particle accelerators have been essential tools of particle physics since initial development in the early twentieth century, with commercial applications soon following each successive advancement.

Dewar
A dewar is a type of cryostat named after Sir James Dewar, the researcher who first developed the concept of a vacuum insulated container with silvered walls to reflect thermal radiation. Dewar was the first to liquefy hydrogen, and he created the device to store his discovery. The thermos bottle...
Stirling and Gifford-McMahon Cryocoolers
Stirling and Gifford-McMahon (GM) cryocoolers are two of the most commonly used cryocoolers in cryogenics. Both devices have a significant industrial base and operate at a wide range of temperatures and capacities. The thermodynamic cycles for both of these cryocoolers are quite similar. The Stirling cycle consists of a compressor,...
Liquefied Natural Gas (LNG)
A significant commercial application of cryogenics is the liquefaction, transport and storage of natural gas. Liquefied Natural Gas (LNG) is generally 95 percent methane with a few percent ethane and much lower concentrations of propane and butane. LNG liquefies at 111.6 K. Unlike many applications of cryogenics, the motivation for...
Cryogenic Electronics
Randall Kirschman, consulting physicist, Mountain View, California ExtElect@gmail.com Cryogenic electronics—the operation of electronic devices, circuits, and systems at cryogenic temperatures—has been a valuable technology for decades. Cryogenic electronics (also referred to as low-temperature electronics, or cold electronics) can be based on semiconductive devices, on superconductive devices, or on a combination...
Particle Physics: High Energy Physics
Cryogenics and High-Energy Physics 1. From symmetry magazine: http://www.symmetrymagazine.org/cms/?pid=1000627: Cryogenics is the study of how materials behave at temperatures near absolute zero. In high-energy particle accelerators, such frigid temperatures reduce the electrical resistance of wires in superconducting magnets, increasing the magnet strength and allowing faster particle acceleration. The same holds...
HTS Degaussing Systems
From the Spring 2009 issue of Cold Facts (Volume 25, Number 2): Thanks to a joint project by the US Navy and a number of industry partners, high temperature superconducting (HTS) technology is now at the heart of an advanced degaussing system aboard the USS Higgins at the naval station...
Magnetic Resonance Imaging
From http://www.superconductors.org: An area where superconductors can perform a life-saving function is in the field of biomagnetism. Doctors need a non-invasive means of determining what’s going on inside the human body. By impinging a strong superconductor-derived magnetic field into the body, hydrogen atoms that exist in the body’s water and...
Pressure for an adiabatic liquefaction of nitrogen
I am a student from Chicago, and I need to calculate the pressure necessary for an adiabatic liquefaction of nitrogen.
Thermal expansion coefficient for LN2, LO2 and LH2
Can anyone help me get a table (or diagram) of different thermal expansion coefficient for different cryogenic liquids (especially LN2, LO2 and LH2)?
Small, low power cryocooler to use in a working prototype device
Where can I find a small, low power cryocooler to use in a working prototype device? Please provide a list of suitable manufacturers.
Looking for super insulation for a cylindrical container
We need super insulation for a cylindrical container of approximately 10 cm in diameter and 10 cm height to be kept at -40 ° Centigrade for less than 24 hours (outside=room temperature).
