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....

WOMEN in CRYOGENICS and SUPERCONDUCTIVITY

Alexandria Burger, Bluefors – Manufacturing Engineer Manager Current projects: My current focus is leading a team to improve manufacturing efficiencies for 2026. These efficiency improvements will not only offset the increasing costs of materials but also allow us to reduce lead times. I also contribute to manufacturing documentation, 6S events,...

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...

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...

Resistance to embrittlement at low temperatures

Could anyone advise me about resistance to embrittlement at low temperatures for the alloys in subject, i.e. does the CF10M perform like the CF8M in the same cryogenic service (-215F)? Amara Maafi Amara.Maafi@bg-group.com

Need help with temperature dependent model

I am a fourth-year student at New Zealand University. My name is Xu Ke. I have a project to generate a temperature dependent model for inductor, capacitor and diode by using PLECS. PLECS is software which acts as a toolbox for MATLAB. In my models, the temperature is very low,...

In what form is water available in LN2?

Does anybody know in what form water is available in LN2? There probably is a block of ice in the bottom of the tank. But as water comes in many shapes, I can imagine snow or crystals floating free in the LN2. When water is available in LN2, could small...

Separating gases using cryogenics

We are looking for some consulting engineers who understand how to separate gases using cryogenics. We have a new process which takes biomass and converts it to 5 gases and we need to separate these gases into their pure forms. Thanks for your help. Malcolm Draper Energy Research Group LLC...
