SNOLAB Confirms Positive First Year of Dark Matter Research

Researchers at the underground SNOLAB in Ontario, Canada, operate its DEAP-3600 experiment and have released results from the team's first year collecting data on dark matter, confirming that the sensitive detector is working as anticipated.

Flow of Time Reversed on Quantum Computer

An international science team reports that it has successfully returned a computer briefly to the past. Such a result suggests new paths for exploring the backward flow of time in quantum systems and also opens the possibility for quantum computer program testing and error correction. Argonne National Laboratory (CSA CSM)...

Scientists Exploring How to Make the Large Hadron Collider Safer

An international research team headed by Russia's Ural Federal University has taken on the task of increasing the reliability of the Large Hadron Collider (LHC) and other complex facilities. Results from the group's experiment were recently published and include proposals for the "second-generation high-temperature superconductors at liquid nitrogen temperatures."

Scientists Chill Nanoelectronics Below a Thousandth of a Kelvin

Tiny electronic chips have been cooled to a record low temperature, dipping below a thousandth of a Kelvin during experiments conducted at Delft University of Technology in the Netherlands.

IBM and University of Chicago Collaborate to Advance Quantum Computing

A new research collaboration between the University of Chicago's Enabling Practical-Scale Quantum Computing (EPiQC) project and IBM is projected to bring quantum computing closer to the present by sharing resources and training the next generation of quantum computer scientists.

Biopsy Snap Frozen within Seconds

The standard procedure for rapid freezing a biopsy taken from a patient involves the use of liquid nitrogen. Such a procedure, however, is not allowed inside operating rooms, thus causing frequent challenges and delays. But researchers at the Netherlands' University of Twente have now developed a "snap freezing" apparatus that...

Transfer Lines

Transfer lines may in some real sense be thought of as the cryogenic fluid analogy of current leads. While current leads carry electrical power to where it’s required in a cryogenic system, transfer lines do the same with cryogenic fluids. Transfer lines range in complexity from very simple U-tubes containing...

Zero Boiloff

Zero Boil Off cryostats are those that contain liquid cryogens but are designed to eliminate or vastly reduce the boil off of the liquid. These cryostats combine some of the advantages of Cryogen-Free systems (e.g. ease of use and long operational lifetime) with the advantages associated with a reservoir of liquid...

Cryomodule

Cryomodule is a term that is most commonly used to refer to cryostats that contain superconducting radio frequency (SRF) cavities. Such cavities are used to accelerate charged particle beams and are a major component of modern particle accelerators. Using the term cryomodule to refer to cryostats containing SRF cavities appears...

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...

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?
