Young Faces: The Next Generation in Cryogenics, Part I

In the Summer 2006 issue of Cold Facts, we debuted a feature story about outstanding young professionals who are active in the cryogenics industry. This year, we again asked the cryogenics community for the names of up-and-coming "young faces." Here is Part I of the third installment of Young Faces,...

BICEP2 and the Outer Edge of the Universe

The first BICEP (Background Imaging of Cosmic Extragalactic Polarization), BICEP1, observed with 49 spider-web bolometers for three years. BICEP2 carried 256 dual polarization transition-edge superconducting detectors of greatly increased sensitivity, and also observed for three years. Dr. Peter Mason reports here on the results of these two instruments and their...

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...

Containing ice accumulation while recovering helium

We are implementing a system to recover helium from our Janis ST-500 continuous flow LHe cryostat. The recovery system uses standard 1/4″ plastic tubing, which we connect directly to the cryostat’s exhaust port. The problem with this setup is that the gas is still quite cold as it leaves the...
