LHC Restarted, Researchers Eye 2,700 Bunches per Beam

The Large Hadron Collider (LHC) resumed operations on March 25 when CERN researchers opened its doors to allow particles to travel around the ring for the first time since the year-end technical stop (YETS) began in December 2015. Several updates and interventions took place in LHC accelerators and beamlines during...

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...

Nexans’ Superconducting Fault Current Limiters Installed in Birmingham Power Grid

Western Power Distribution has integrated two 12 kV superconducting fault current limiters (sFCL) from Nexans Deutschland GmbH (CSA CSM) into the Birmingham UK power grid. The installation is part of FlexDGrid, a £17M project that aims to both reduce power cuts and carbon emissions and to increase the capacity of...

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...

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...

Cryobiology

Andreas Sputtek Past President Society for Cryobiology sputtek@uke.uni-hamburg.de or http://www.sputtek.de/. The word cryobiology (from the Greek words “cryo” = cold, “bios” = life, and “logos” = science) literally signifies the science of life at low temperatures. In practice, this field comprises the study of any biological material or system (e.g.,...

Cryogenic Insulation

James E. Fesmire Cryogenics Test Laboratory NASA Kennedy Space Center james.e.fesmire@nasa.gov Introduction In today’s world, the use of cryogenics and low-temperature refrigeration is taking a more and more significant role. From the food industry, transportation, energy, and medical applications to the Space Shuttle, cryogenic liquids must be stored, handled, and...

Cryogenic Treatment of Materials

F.J. Diekman Controlled Thermal Processing, Inc. info@metal-wear.com Cryogenic Processing (also called cryogenic treatment, and incorrectly “cryogenic tempering”) is a process that uses cryogenic temperatures to modify materials to enhance their performance. Cryogenic Processing involves the slow reduction in temperature of the material to at least -300°F (-185°C) and holding the...

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...

Sudden loss of vacuum in LHe storage dewar

I’m trying to find data on what happens when a 100 Liter LHe storage dewar experiences a catastrophic failure such as a sudden loss of vacuum. If anyone has any info on this subject, it would be very helpful.

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?
