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,...

HiLumi LHC: cryogenics equipment arrives underground

By Corinne Pralavorio The vertiginous descent of equipment into the depths of the accelerator tunnels is always a captivating event. The stars of the show over the last few weeks have been the two gleaming cold boxes that have arrived in the new service tunnels of the High-Luminosity LHC (HiLumi...

Pelican Wire Designs for Cryogenic and Extreme Energy Systems

As renewable energy, electrification and advanced research technologies continue to expand, the demands placed on wire and cable systems are evolving just as rapidly. Higher power densities, tighter system integration and increasingly extreme operating environments are pushing manufacturers beyond traditional commodity wire solutions. Caleb Lemmons, Business Development Manager at Pelican...

From Cryogenic to Red-Hot: Optical temperature sensing from 77 K to 873 K

by University of Innsbruck An international collaboration involving researchers from the University of Innsbruck has developed a novel luminescent material that enables particularly robust and precise optical temperature sensing across an exceptionally broad temperature range. Optical luminescence thermometry has been gaining increasing attention, as it allows contactless temperature measurement even under...
Researchers at QuTech, working on a Fujitsu-funded project, have developed the first cryogenic control chip able to directly control both electron and nuclear spins in diamond-based qubits.

Scalable Diamond Quantum Computing with Cryogenic Chip Integration

NV centers are among the most promising qubit platforms, combining fast electron-spin control with exceptionally stable nuclear-spin memories. However, until now, these systems have depended on room-temperature electronics connected by long cables to the cryogenic environment: a setup that considerably hinders scalability and reliability. The new cryo-CMOS controller solves this...

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...

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...

Cryogenic Treatment of Materials

F.J. Diekman Controlled Thermal Processing, Inc. info@metal-wear.com Cryogenic Processing (also called cryogenic treatment, and incorrectly “cryogenic tempering”) is a process that uses cryogenic temperatures to modify materials to enhance their performance. Cryogenic Processing involves the slow reduction in temperature of the material to at least -300°F (-185°C) and holding the...

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...
