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)...

Space Cryogenics

Space cryogenics is, somewhat obviously, the application of cryogenics to space exploration and science. The use of cryogenics in space optimizes the launching of vehicles, provides power and life support to spacecraft and is critical for many scientific observations.Space cryogenics has a number of challenges and has driven both pure...

Exergy

The science of thermodynamics plays a major role in cryogenics. It underlies the various refrigeration cycles, from Carnot to Brayton (Cold Facts Vol. 32 No. 2) and Joule-Thomson, is a fundamental part of the definition of terms such as coefficient of performance (Cold Facts Vol. 31 No. 1) and even...

Cryogenic Treatment

Cryogenic treatment is the process of cooling materials to cryogenic temperatures temporarily to improve their material properties at room temperature. This is distinct from cooling materials down to cryogenic temperatures to take advantage of phenomena such as superconductivity that only occur at cryogenic temperatures. Cryogenic treatment, sometimes also referred to...

Magnetic Levitation

From http://www.superconductors.org. Magnetic-levitation is an application where superconductors perform extremely well. Transport vehicles such as trains can be made to “float” on strong superconducting magnets, virtually eliminating friction between the train and its tracks. Not only would conventional electromagnets waste much of the electrical energy as heat, they would have...

Superconductivity

From Superpower website. History of Superconductivity Superconductivity was discovered in 1911 by the Dutch physicist, Heike Kammerlingh Onnes when he was able to liquefy helium by cooling it to 4 Kelvin, or -452°F. This enabled him to cool other materials close to absolute zero and investigate their electrical properties. He...

Medical Applications of Cryogenics

Neutron Therapy Cryogenics is at the heart of nuclear accelerators. Accelerators such as Fermilab’s Tevatron make neutron therapy for cancer possible. From Fermilab Today 4/20/09: Fermilab currently offers neutron therapy. But staff at Fermilab designed and built the proton accelerator used by the nation’s first hospital-based treatment center to use...

Nuclear Physics

Al Zeller National Superconducting Cyclotron Lab (NSCL) at Michigan State University zeller@nscl.msu.edu Cryogenics has a long history in nuclear physics. The technology has its origins in the use of cold traps for maintaining a vacuum, which is required to prevent beam loss and for generating high voltages used in acceleration....

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...
