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.
FDA Suggests Avoidance of Food Products Made with Point of Sale Liquid Nitrogen
The US Food and Drug Administration alerts consumers and retailers of the potential for serious injury from eating, drinking or handling food products prepared by adding liquid nitrogen at the point of sale, immediately before consumption.
New Editors Named for International Cryogenics Monograph Series
The Springer publishing company recently named Dr. Sangkwon Jeong and Dr. John Weisend II as new editors for its International Cryogenics Monograph Series. The ICMS series was first established in the early 1960s and has provided a forum for active researchers to report on past developments and present work in...
TRIUMF Celebrates New Five-Year Plan
The scientific community at TRIUMF (CSA CSM) recently gathered at its Advanced Rare Isotope Laboratory to celebrate the new Five-Year Plan for 2020-2025. It defines both the vision and mission for Canada's particle accelerator center, communicating the lab’s goals and strategies while laying out an action plan for the specified...
Lockheed Martin Reveals Human Lunar Lander Concept
Lockheed Martin revealed its concept for a crewed lunar lander during the International Astronautical Congress (IAC) in Bremen, Germany, showcasing how the reusable lander would align with NASA's lunar Gateway and future Mars missions.

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).
