2022 Women in Cryogenics

Each year, CSA celebrates women in the fields of cryogenics, superconductivity, and quantum in our annual Women in Cryogenics feature. This year, we meet eight women across various sub-industries of cryogenics who are not only making great accomplishments and impacts in their fields of work, but also who provide powerful advice for how...

Large Hadron Collider Comes Back to Life After Three-year Hiatus

The world’s most powerful particle accelerator—the Large Hadron Collider (LHC)—has sprung back to life after a three-year shutdown. After planned maintenance and upgrades, the Large Hadron Collider has been turned back on and will shortly start another run of cutting-edge experiments. The LHC, in Switzerland, was switched off in December 2018...

USC’s New Cryogenic Electron Microscopy Facility Officially Opens for Business

USC’s new cryogenic electron microscopy (cryo-EM) facility, featuring state-of-the-art instrumentation capable of imaging molecules, garnered the spotlight during a recent symposium celebrating the facility’s official grand opening. Scientists and officials from USC, biotechnology giant Amgen, Thermo Fisher Scientific, and noted academic research institutions gathered for the event, held in March at...

Ultra-lightweight Cryogenic Tank Aids Aircraft Industry Endeavors

California-based firm HyPoint is developing an innovative cryogenic tank design that could massively boost the range of hydrogen-powered aircraft, a press statement reveals. HyPoint’s technology is extremely lightweight compared with traditional fuel cells and it could allow airliners to fly up to four times farther than traditional passenger aircraft. A 50-56 passenger...

Elusive superconducting-transition signature seen for the first time

Researchers in the US report that they have observed the so-called “fourth signature” of superconducting phase transitions in materials known as cuprates. The result, obtained via photoemission spectroscopy of a cuprate called Bi2212, could shed fresh light on how these materials, which conduct electricity without resistance at temperatures of 77...

Latest in Defining Cryogenics

Refrigerators and Liquefiers

Two of the most common terms used in cryogenics are “refrigerator” and “liquefier.” These terms describe similar and, as will be seen, in some cases identical components. A refrigerator provides cooling (that is, absorbs heat) at cryogenic temperatures. Refrigerators typically put a working fluid (such as helium) through one of...

Air Separation

Air separation is one of the largest, as well as earliest, industrial applications of cryogenics. In this process, cryogenic temperatures are used to separate air into its constituent gases: nitrogen (78.08%), oxygen (20.95%), argon (0.93%) and carbon dioxide (0.3%). Trace gases such as krypton, neon, xenon and helium total far...

Coefficient of Performance and Figure of Merit

The coefficient of performance (COP) is used to describe the effectiveness of refrigerators, including those operating at cryogenic temperatures. The COP is defined as the amount of heat removed at the cryogenic operating temperature of the refrigerator divided by the amount of work that must be applied to remove the...

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....

An Issue of Pressure and Flow Rate in a Supply Tank

Please help solve this problem: A supply tank requires a vaporizer to generate sufficient pressure to pump stored fluid up into a vehicle or tank. The available head is limited as the tank level falls and it is important to minimize the system pressure drop to maintain the desired flow...

Using MLI on VJ Line Joints or Cryo Storage Tanks

When installing Multi Layer Insulation (MLI) blankets on VJ line joints or cryo storage tanks should they be wrapped and tied down tight or loose? These are usually pre-cut to size. Also should they have an access hole at the point of where the molecular sieve is installed to help...
