APS Joins SCOAP3 Consortium

CERN, the European Organization for Nuclear Research, and the American Physical Society (APS) have entered into an agreement through SCOAP3 to provide open access to high-energy physics articles published in APS journals. The partnership, which begins in January 2018, covers articles from Physical Review C, Physical Review D and Physical...

NCIS Bungles Investigation, Conflates Cryogenics and Cryonics

A recent episode NCIS, a popular CBS police procedural, featured a villain who killed his victims with liquid nitrogen, interring them alive inside a homemade cryonics chamber. During the big reveal, the NCIS writers conflate cryonics with cryogenics, using one of the show's trope scientific experts to present the latter...

CSA Board Member Joins Superconductivity Center at FSU

Florida State University has hired Lance Cooley, CSA board member and a scientist at the Fermi National Accelerator Laboratory (CSA CSM), to join the Applied Superconductivity Center (ASC) at the FSU-based National High Magnetic Field Laboratory. He will also have a faculty appointment in the Department of Mechanical Engineering at...

Physicists Observe Negative Mass in Bose-Einstein Condensate

Washington State University physicists have created a fluid with negative mass. Push it, and unlike every physical object in the known world, it doesn’t accelerate in the direction it was pushed. It accelerates backward. Led by Peter Engels, WSU professor of physics and astronomy, the researchers generated the conditions for...

O”H” What a Feeling, Toyota Introduces Hydrogen Powered Semi

Toyota has announced a new zero-emission hydrogen fuel cell system designed for semi-truck use at the Port of Los Angeles. Dubbed "Project Portal," the proof of concept vehicle was unveiled at a press conference with port officials and representatives from the California Air Resources Board and the California Energy Commission....

European XFEL Commissions Its Particle Accelerator

The European XFEL has successfully commissioned the particle accelerator that will drive its X-ray laser. When fully operational, the research facility will produce up to 27,000 X-ray laser flashes per second, each so short and intense that researchers can make pictures of structures and processes at the atomic level. The...

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...

Wind Tunnels

Dr. Robert Kilgore The development of the cryogenic wind tunnel is one of many significant breakthroughs in both cryogenics and wind-tunnel technology made during the past millennium. Interest in the development of high-speed commercial and military aircraft resulted in a review of problems of flow simulation in transonic wind tunnels...

History of Cryogenics

From the Fall 1999 issue of Cold Facts magazine Millennium Breakthroughs A variety of CSA members give different perspectives on the past millennium: What were the most significant breakthroughs in cryogenics during the past millennium? Prof. R.G. Scurlock, Kryos Technology, scurlock@soton.ac.uk (“Breakthrough” = way through obstacles — Oxford English Dictionary)...

Cryobiology

Andreas Sputtek Past President Society for Cryobiology sputtek@uke.uni-hamburg.de or http://www.sputtek.de/. The word cryobiology (from the Greek words “cryo” = cold, “bios” = life, and “logos” = science) literally signifies the science of life at low temperatures. In practice, this field comprises the study of any biological material or system (e.g.,...

Cryogenic Insulation

James E. Fesmire Cryogenics Test Laboratory NASA Kennedy Space Center james.e.fesmire@nasa.gov Introduction In today’s world, the use of cryogenics and low-temperature refrigeration is taking a more and more significant role. From the food industry, transportation, energy, and medical applications to the Space Shuttle, cryogenic liquids must be stored, handled, and...

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...

Separated layers of ice over a pipe

I want to know that why there are different layers of ice over a pipe carrying a cryogenic fluid, each layer separated with clear marks / lines? What do these layers signify?
