zeroBOG™ Empowers Sustainable Operations
by Lennis Perez and Edward Tay, Sulzer The need for efficient and sustainable management of cryogenic gases extends far beyond traditional LNG applications. Enabling the recovery and reuse of boiloff gases, or BOG, across sectors such as hydrogen, e-methane and ammonia, supports the transition to low-carbon fuels and helps operators...
Liquid Air Comes of Age in Manchester
by Mark Vyvyan Robinson, Business Development Director, Highview Power As electricity systems integrate increasing volumes of renewable generation, the requirement for long-duration energy storage has become a defining challenge of the global energy transition. In northwest England, the city of Manchester and the surrounding Greater Manchester region are now home...
NASA Inches Closer to Martian Laser Communication
by Charlie Danaher, Danaher Cryogenics Bridging Interplanetary Distances Having a conversation between someone on Earth and Mars is not as science fiction as it used to be. That is thanks to scientists at NASA’s Jet Propulsion Laboratory (JPL) in Southern California and their successful demonstration of the Deep Space Optical...
Vacuum Chambers Answer Quantum Demands and UHV Transfer Needs
by Mel Janecka, Atlas Technologies Quantum computing companies and research facilities often find aluminum and titanium vacuum chambers to be better equipped to maintain purity and ultrahigh-vacuum (UHV) status. Plus, the chambers are non-magnetic and perform effectively within cryogenic conditions, critical for keeping qubits stable. Qubits, the basic units of...
Kathleen Amm’s Evolution in Cryo
When Kathleen Amm describes how she entered cryogenics, she does not point to a single defining moment. Instead, her path began with movement. In the early 1990s, she followed her thesis advisor Justin Schwartz from the University of Illinois to Tallahassee as the National High Magnetic Field Laboratory was opening....

Helium-3
Helium-3 (3He) is one of the two stable isotopes of helium. The other is the much more common Helium-4 (4He). Neither of these isotopes should be confused with He II, which is the second liquid phase of 4He. He II was discussed in this column in the Spring 2010 edition...
Cryopumping
Cryopumping refers to the use of cryogenic temperatures to produce vacuum in enclosed spaces. More broadly, it can also refer to the removal of gases via cryogenic temperatures from a flow stream or enclosure without necessarily resulting in vacuum pressures. This is an important application of cryogenics and is used...
Thermal Acoustic Oscillations
Thermal Acoustic Oscillations (TAO) are a common event in cryogenic systems that can have significant adverse effects on the performance of the system. TAOs are sustained pressure oscillations that can occur in tubes containing gas, closed at one end (the warm end) that have a very large temperature gradient along...
Cryogenics in Space
Peter Kittel University of California-Berkeley pkittel@cal.berkeley.edu Space Cryogenics is the application of cryogenics to space missions. These applications fall into two broad areas, supporting space science missions and supporting the space transportation infrastructure. Science applications: The atmosphere is opaque to much of the electro-magnetic spectrum. In space, the absence of...

Abstract: Cryosurgery is a surgical technique that employs freezing...
Liquefied Natural Gas
Liquefied Natural Gas as it relates to the Field of Cryogenics John W. Bonn VJ Systems, LLC johnbonn@vjsystems-lic.com Today the world is looking for a cleaner fuel and Liquefied Natural Gas (LNG) plays a large part in achieving this goal. LNG in a liquid form is at -162°C (-259°F) and...
Food Processing
Cryogenics and Food The industrial gas industry provides a host of products and services related to food. The various gases have useful and sometimes fascinating applications in food industry. “The food industry is not a homogenous industry. The needs of customers processing hamburger vs. poultry vs. strawberries vs. seafood, for...
Looking for the thermal conductivity of the high density polyethylene (HDPE) between 1.9 and 10K
I am looking for the thermal conductivity of the high density polyethylene (HDPE) between 1.9 and 10K (or even up to higher temperatures). The best would be to have these data for the HDPE material which sold by the CERN shop, which has a density of 0.95 g/cm3. Pier Paolo...
What is "Alpha" cryogenic processing?
Can somebody please tell me what the “Alpha Cryogenic Process” is? How is it different from ordinary cryogenic processing? Bernd Ahne, HiFi-Tuning
Do Stirling coolers have any relation to Stirling engines?
I was just wondering, do Stirling coolers have any relation to Stirling engines?
What type of MLI should be used in LOX (VJ) lines and flex hoses?
I work for ASRC Aerospace at the Kennedy Space Center (KSC). We support NASA in ground support equipment (GSE) design. I have a question concerning the type of multilayer insulation (MLI) to use in LOX vacuum Jacketed (VJ) lines and flex hoses.
