Cryogenics at the European Spallation Source

The European Spallation Source (ESS) is an intergovernmental project building a multidisciplinary research laboratory based upon the world’s most powerful neutron source. The facility will be built in Lund, Sweden. The ESS will use a linear accelerator (linac), which will deliver protons with 5 MW of power to the target...

Cryogenics Conference Moves to Dresden

Held in Dresden, Germany, for the first time, September 11-14, the international Cryogenics conference attracted 150 participants from 23 nations with 54 lectures and 28 posters presented. The exhibition comprised 18 companies. Students from the European Course of Cryogenics, sponsored by TU Dresden, which was held in the city at...

UH wind turbine superconductivity research project wins additional funding

A University of Houston engineering researcher and his team have received additional funding from the US Department of Energy (DOE) for a wind energy project that involves using superconducting wire to generate and transport electricity.

Fermilab scientists selected as APS fellows

Five Fermilab scientists have been named fellows of the American Physical Society, a distinction awarded each year to no more than one-half of 1 percent of current APS members by their peers.

Nexans and AMSC introduce fault current limiter for North American utilities

AMSC, a global solutions provider serving wind and grid leaders, and Nexans, an expert in the cable industry (both CSA Corporate Sustaining Members), recently introduced to the North American market a medium voltage superconductor fault current limiter (SFCL) solution that is designed to meet many of the challenges caused by...

“Crowning” the ITER cryostat from below solves columnar design problem

Columns are as old as civilization: for thousands of years, they have provided architects and engineers with a simple and sturdy solution to support heavy loads while leaving room to move around on the ground below. This traditional and reliable solution was to be implemented in ITER.

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...

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...

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...

Need help comparing chest freezers and upright freezers

Currently we use in our Biobank an upright -80 freezer to store all our samples. We are planning to buy a fully automated bio-repository storage that will do the picking of samples under restricted conditions. But in the meantime I foresee that we have to pick the samples manually. The...

Need recommendations for cryogenic vials

I am looking into standardizing our range of bio storage tubes (cryogenic vials). These will be for both blood and tissue samples and their derivatives. Any recommendations, comments on Micronics, Nalgene, Nunc and or others that are suitable for long term -80 C and -196 C storage, DNA/RNA suitable, would...

We need a custom machine for flash freezing of water

We are an ice making company and have started a new project, which is related to flash freezing of water. It is based on cryogenics technology and we need a custom made machine. I would kindly ask you to pass me a few companies who would be interested in such...

Looking for a pump suitable for cold liquids

I would like to construct a small cooling circuit (appr. 50 x 50 cm) pumping liquid at a temperature down to -120°C from a cold reservoir to the specimen to be cooled. The tubes and connections are not a problem, but does somebody know a pump (suction/compression for circulation) suitable...
