Cryogenic Systems Enable SOFIA Space Project

An interview with Nans Kunz, Senior Engineer at NASA Ames Research Center, and former SOFIA Chief Engineer. The Stratospheric Observatory for Infrared Astronomy (SOFIA) project is a telescope carried in a 747 aircraft up above the atmosphere. Kunz explains how cryogenics made the project more cost-effective and efficient.

US Postal Service honors Professor John Bardeen

A US postage stamp commemorating the late UI physics Professor John Bardeen, inventor of the transistor and a two-time Nobel Prize Winner, was officially issued at Postage Stamp Mega-Event in New York's Madison Square Garden.

Ganni Cycle saves BNL in weekly electric costs

The "Ganni Cycle", invented by engineers at Thomas Jefferson National Accelerator Facility, has been saving Brookhaven National Laboratory approximately $50,000 a week in electric costs for the Relativistic Heavy Ion Collider (RHIC).

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...

What is the temperature range of cryogenics?

Could you please tell me what is the temperature range of cryogenics? In other words, is -100°F considered cryogenic, or does it start lower? Could I expect to see some extended life in D2 stamping dies? What would the recipe be to achieve the desired results using cryogenics?
