Cryogenic Technique Reveals Fraudulent Food and Drugs

Engineers from the University of California, Riverside have developed "chronoprinting," a new technique that can detect fake drugs and food using videos recorded while samples undergo alterations. The technology requires only a few relatively inexpensive pieces of equipment, free software to accurately distinguish pure from inferior food or medicine and...

NASA’s JPL Seeking Applicants for First Space Accelerator

NASA's first aerospace accelerator program will select 10 startup companies to take part in a three-month pilot program to develop new technologies for space. Applications will be accepted through April 7. Selected teams will develop concepts and business plans over a three-month period and then pitch their results to the...

TRIUMF Receives Historic Canadian Investment

The Government of Canada has announced a five year and $292.7M investment supporting laboratory operations at TRIUMF (CSA CSM). The donation comes in response to TRIUMF's recently published Five-Year Plan 2020-2025 and represents the country's largest single investment there to date.

Fermilab Breaks Ground on PIP-II

Fermi National Accelerator Laboratory (CSA CSM) has officially broken ground on a major new particle accelerator project that will power cutting-edge physics experiments for many decades to come. When complete, PIP-II will become the heart of the laboratory’s accelerator complex, vastly improving what is already the world’s most powerful particle...

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)...

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...

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?
