Resurrected Detector Will Hunt for Some of the Strangest Particles in the Universe

Brought from Italy's Gran Sasso National Laboratory two years ago, ICARUS—an outdated acronym for Imaging Cosmic And Rare Underground Signals—will soon start a second life seeking perhaps the strangest particles physicists have dreamed up, oddballs called sterile neutrinos. Icarus will resume the neutrino hunt at Fermilab. If they exist, sterile...

Aerogel Could Be a Key Building Material for Mars

NASA scientists are exploring how aerogel, a translucent, Styrofoam-like material, could be used as a building material on Mars. Aerogel retains heat; structures built with it could raise temperatures enough to melt water ice on the Martian surface.

North Dakota Cattle Ranchers Now Have an Alternative to Hot Branding

Under North Dakota House Bill 1166, freeze branding became a legal method for ranchers to show ownership of cattle, according the North Dakota Stockmen’s Association. Freeze branding uses dry ice or liquid nitrogen to cool a branding iron, which is then pressed into an animal’s hide to mark it for...

Chart Industries Supplies Nitro Beverage Manufacturers

Chart liquid nitrogen dosing technology supports and expands the distribution of Cold Brewed Coffee. Liquid nitrogen dosing adds pressure in the can for the packaging process.

Young Professionals 2019: The Next Generation in Cryogenics Part 2

Young Professionals 2019 Part 2 introduces outstanding young professionals (under 40 years of age) who are doing interesting things in cryogenics and superconductivity and who show promise of making a difference in their fields.

CERN Successfully Tests Cooler Way to Transport Electricity

A 60-meter-long line has been developed for CERN’s future accelerator, the High-Luminosity LHC, which is due to come into operation in 2026. Tests began last year and the line has transported 40,000 amps, 20 times more than what is possible at room temperature with ordinary copper cables of a similar...

Dewar

A dewar is a type of cryostat named after Sir James Dewar, the researcher who first developed the concept of a vacuum insulated container with silvered walls to reflect thermal radiation. Dewar was the first to liquefy hydrogen, and he created the device to store his discovery. The thermos bottle...

Stirling and Gifford-McMahon Cryocoolers

Stirling and Gifford-McMahon (GM) cryocoolers are two of the most commonly used cryocoolers in cryogenics. Both devices have a significant industrial base and operate at a wide range of temperatures and capacities. The thermodynamic cycles for both of these cryocoolers are quite similar. The Stirling cycle consists of a compressor,...

Liquefied Natural Gas (LNG)

A significant commercial application of cryogenics is the liquefaction, transport and storage of natural gas. Liquefied Natural Gas (LNG) is generally 95 percent methane with a few percent ethane and much lower concentrations of propane and butane. LNG liquefies at 111.6 K. Unlike many applications of cryogenics, the motivation for...

Bose-Einstein Condensate

A Bose-Einstein condensate, first proposed in 1925 by Albert Einstein based on work done by Satyendra Nath Bose (the same Bose from whom the term boson is derived), is a super-cold state of matter in which almost all of the individual atoms have “condensed” down to the lowest possible quantum...

Cold Technology for Pest Control

While it does not reach temperatures cold enough to be called cryogenic, carbon dioxide snow is at the heart of a new way of dealing with unwanted pests. It utilizes a quick freezing process that takes advantage of the properties of carbon dioxide snow and has a number of benefits...

Definition or max temp which defines “cryogenic”?

Please help me with a definition: I am calculating material and fabrication costs for a quote for a hydrocarbon meter station.

Thermal shock on steel cylinder when dropped into liquid nitrogen

We are a research team at the University of South Florida, studying the “thermal shock” on a steel cylinder when it is dropped into liquid nitrogen. We want to make sure that the thermocouple does not get influenced by the surrounding LN2. Any advice?

Getter materials to absorb out gassed materials?

Here’s one for the scientists: We would like to sell vacuum insulated pipe for high temperature fluid applications. Are there any good getter materials that we can place in the vacuum space of our VJP to absorb outgassed materials at elevated temperatures?

Data on Carbon Fibres Reinforced Plastic at temperatures between 4 and 300K.

I am looking for data on Carbon Fibres Reinforced Plastic at temperatures between 4 and 300K. I would appreciate it if someone could give me some hints on where to find it.
