LCLS-II Upgrade Will Boost Power of World’s Brightest X-ray Laser

Construction is underway on a major upgrade to LCLS (Linac Coherent Light Source), a unique X-ray laser at the Department of Energy’s SLAC National Accelerator Laboratory. The project, known as LCLS-II, will add a second X-ray laser beam that’s 10,000 times brighter, on average, than the first one and fires...

NASA Completes JWST Cryogenic Testing

NASA researchers have completed cryogenic testing on the science instruments module for the James Webb Space Telescope (JWST). The module contains JWST's science cameras and spectrographs, and had been undergoing four months of monitoring inside a giant thermal vacuum chamber called the Space Environment Simulator (SES) at NASA's Goddard Space...

NASA Scientists Prepare Cold Atom Laboratory for ISS Mission

On a sun-drenched hill in Southern California's San Gabriel Mountains, researchers at NASA's Jet Propulsion Laboratory in Pasadena are making progress on an experimental facility that could create the coldest known place in the universe. It's called the Cold Atom Laboratory (CAL) and is expected to probe the wonders of...

FabLab, a STEM Show for Teen Girls, Launches on FOX

FabLab, a new science television series from the producers of the Teen Choice Awards, has launched on FOX. The show aims to enthuse tween and teen girls about STEM by drawing connections between STEM innovations and efforts to make the world a better place. FabLab is produced in partnership with...

NIST Develops First Widely Useful Measurement Standard for Breast Cancer MRI

Researchers at the National Institute of Standards and Technology (NIST) have developed the first widely useful standard for magnetic resonance imaging (MRI) of the breast, a method used to identify and monitor breast cancer. The NIST instrument—a “phantom”—will help standardize MRIs of breast tissue and ensure quality control in comparing...

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...

Cryogenics in Space

Peter Kittel University of California-Berkeley pkittel@cal.berkeley.edu Space Cryogenics is the application of cryogenics to space missions. These applications fall into two broad areas, supporting space science missions and supporting the space transportation infrastructure. Science applications: The atmosphere is opaque to much of the electro-magnetic spectrum. In space, the absence of...

Liquefied Natural Gas as it relates to the Field of Cryogenics John W. Bonn VJ Systems, LLC johnbonn@vjsystems-lic.com Today the world is looking for a cleaner fuel and Liquefied Natural Gas (LNG) plays a large part in achieving this goal. LNG in a liquid form is at -162°C (-259°F) and...

Food Processing

Cryogenics and Food The industrial gas industry provides a host of products and services related to food. The various gases have useful and sometimes fascinating applications in food industry. “The food industry is not a homogenous industry. The needs of customers processing hamburger vs. poultry vs. strawberries vs. seafood, for...

Specs and info on turbo expanders

I am a fourth year chemical engineering student doing a design project for the liquefaction of natural gas to DME and we are using a turbo expansion unit. I was wondering whether you would send me some specs and any additional information on turbo expanders that I could use as...

Colleges that offer cryogenic studies

Would you happen to know of any colleges in the US that offer cryogenics as a major? If not, should I major in something like biology or physics before, then branch off to the field of cryogenics? Any information that you could give me would be greatly appreciated, considering this...

Data on hardness of Indium?

Where can I find experimental data on the hardness of Indium, as a function of temperature, as well as any existing data on the thermal contact conductance of junctions containing Indium foil, also as a function of temperature?
