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 II

Helium II (He II) refers to the second liquid phase of the most abundant helium isotope (4He). Helium II is also referred to as superfluid helium. Helium II occurs once the temperature of the liquid helium drops below 2.17K. The phase transition between the first liquid phase of Helium (referred...

Magnetic Levitation

From http://www.superconductors.org. Magnetic-levitation is an application where superconductors perform extremely well. Transport vehicles such as trains can be made to “float” on strong superconducting magnets, virtually eliminating friction between the train and its tracks. Not only would conventional electromagnets waste much of the electrical energy as heat, they would have...

Superconductivity

From Superpower website. History of Superconductivity Superconductivity was discovered in 1911 by the Dutch physicist, Heike Kammerlingh Onnes when he was able to liquefy helium by cooling it to 4 Kelvin, or -452°F. This enabled him to cool other materials close to absolute zero and investigate their electrical properties. He...

Medical Applications of Cryogenics

Neutron Therapy Cryogenics is at the heart of nuclear accelerators. Accelerators such as Fermilab’s Tevatron make neutron therapy for cancer possible. From Fermilab Today 4/20/09: Fermilab currently offers neutron therapy. But staff at Fermilab designed and built the proton accelerator used by the nation’s first hospital-based treatment center to use...

Nuclear Physics

Al Zeller National Superconducting Cyclotron Lab (NSCL) at Michigan State University zeller@nscl.msu.edu Cryogenics has a long history in nuclear physics. The technology has its origins in the use of cold traps for maintaining a vacuum, which is required to prevent beam loss and for generating high voltages used in acceleration....

Power usage: cryogenic systems vs. regular refrigerators

A recent project highlighted to me that closed cycle cryogenic cooling systems use far more electrical power to reduce temperatures by a few watts than regular refrigerators. I am sure it must be something to do with the extra difficulty of removing the heat from the liquid nitrogen or similar...

Redundancy strategies for mechanical -80C freezers

I was wondering what kind of redundancy strategies are people using for their mechanical -80C freezers? I am aware of the following. Please add if you are doing something different. 1) 1 Backup freezer for every 10 freezers – Empty and maintained at -80C at all times 2) Backup C02...

Method to move components in a cryogenic environment

Does anyone know of a method with which to reliably move components in a cryogenic environment? We are interested in moving detectors in a cryogenically cooled (2K) vacuum chamber, which is contained within a larger cryostat/isolation vacuum with thermal shields. As the desired horizontal or vertical displacement is between 10...
