REBCO HTS Wire Manufacturer SuperPower Relocates to New Facility

On August 24, SuperPower Inc. (CSA CSM), a wholly owned subsidiary of Japan’s Furukawa Electric Company, Ltd., announced that it has completed its move and is now operating from a new facility in Glenville NY. The company is a world leader for the development and manufacturing of REBCO-based second generation...

Berkeley Lab Selected to Lead Next-Generation Cosmic Microwave Background Experiment

The largest collaborative undertaking yet to explore the relic light emitted by the infant universe has taken a step forward with the US Department of Energy’s selection of Lawrence Berkeley National Laboratory (Berkeley Lab) to lead the partnership of national labs, universities and other institutions that will carry out the...

Cryogenics Contributes to Lifesaving Pandemic Treatments, Research

For the past seven months, the US has been fighting alongside the rest of the world to reign in COVID-19. From cutting-edge research and technical developments to recovery routines and last-line-of-defense treatments, cryogenics has played a number of roles—some expected and some surprising—to aid in the international response to the...

Birth of Cloned Przewalski’s Foal Offers Genetic Diversity for Endangered Species

On August 6, 2020, the world’s first successfully cloned Przewalski’s horse was born in Texas at the veterinary facility of a ViaGen Equine collaborator, Timber Creek Veterinary. The foal, born to a domestic surrogate mother, is a clone of a male Przewalski’s horse whose DNA was cryopreserved 40 years ago...

ASC 2020 Is Ongoing

The organizers of the 2020 Applied Superconductivity Conference are presenting a completely virtual conference through November 7, 2020. The two-week format aims to accommodate international attendance and make viewing presentations convenient and easy to experience. https://ascinc.org/registration/

International Cryocooler Conference to Be Virtual-Only

Given the continuing COVID-19 pandemic with restrictions on travel and group meetings, the organizers of the International Cryocooler Conference (ICC) have moved the meeting date to December 7-10, 2020, as a totally virtual conference with no on-site attendance using Zoom® as the primary media. https://cryocooler.org

Liquid Hydrogen

Hydrogen becomes a liquid at 20K and 1 bar. Liquid hydrogen (LH2) is an important substance in industry, transportation and research. Industrial uses of hydrogen include applications in the electronics, glass, chemical and metal processing fields. In these applications, the hydrogen is generally used as a room temperature gas but...

Superconducting Radiofrequency Cavities

Superconducting radio frequency (SRF) cavities represent an important application of cryogenics and superconductivity. SRF cavities are a technology for accelerating charged particle beams via the transfer of radiofrequency (RF) energy to the beams via resonant structures. As such, they are frequently found in large particle accelerators used for scientific research....

Thermal Radiation Shields

Actively cooled thermal radiation shields are a common feature of cryostats whose lowest temperature is less than 77K. These shields, which typically operate at temperatures between that of LN2 and 40K, block thermal radiation from higher temperatures from reaching lower temperature cryogenic components or fluids. Since the heat radiated from...

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...
