CERN Events Encourage Next Generation of Women in Science

In physics, as in many other branches of science, there is often a huge gap between the number of men and women. At CERN, for example, only 20 percent of the community are women. In an attempt to encourage and attract more women to choose science—and particularly physics—as a career,...

CSA Mourns Peter Gifford, a Friend, Colleague and Industry Leader

Peter Gifford, longtime leader of Cryomech Inc., has passed away at 69. Gifford was a fixture in the cryogenic community, a dedicated member of CSA and one of the second-generation industry leaders affectionately dubbed the “Cryomafia.” Under Gifford’s leadership, Cryomech has been a longstanding and strong supporter of CSA as...

CSA Mourns Kathryn Meyer

We regret to report the death of Kathryn Meyer, 88, wife of the late Frank Meyer, founder of Meyer Tool and Manufacturing, Inc., and mother to Eileen Cunningham, the company's current president. Her funeral was held on Jan. 28. Memorial contributions to the Fisher Center for Alzheimer's Research Foundation can...

What I Learned From My Mentors

CSA’s new board members reveal their most influential mentors in “What I Learned From My Mentors,” discussing where they worked together and ways the relationships advanced their careers.

Chart Industries Acquires Hetsco

Chart Industries, Inc. has acquired Hetsco, Inc. in a $22 million deal made through its subsidiary, Chart Lifecycle, Inc. The move, according to a Chart statement, supplements the company's current offerings by bringing a full suite of welding services for industrial gas and gas processing facilities including mission critical repair,...

Toward a Standardized ODH Analysis Technique

Standardization of ODH analysis and mitigation policy thus represents an opportunity for the cryogenic community. There are several benefits for industry and government facilities to develop an applicable unified standard for ODH. The number of reviewers would increase, and review projects across different facilities would be simpler. It would also...

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...

Magnets

From “Superconductivity: Present and Future Applications” by the Coalition for the Commercial Application of Superconductors. Particle physics uses accelerators to recreate the conditions of the early universe in an attempt to piece together the complex puzzle of how we got to where we are today. These huge machines are used...

Energy Storage

From “Superconductivity: Present and Future Applications” by the Coalition for the Commercial Application of Superconductors. With power lines increasingly congested and prone to instability, strategic injection of brief bursts of real power can play a crucial role in maintaining grid reliability. Small-scale Superconducting Magnetic Energy Storage (SMES) systems, based on...

Astronomy

ASTRONOMY IN SPACE by Peter V. Mason, retired, Jet Propulsion Laboratory, and Visiting Associate, California Institute of Technology. Pmason@alumni.caltech.edu In thinking about the reasons to perform astronomy in space, we first consider the effect of the earth’s atmosphere. On a scale of decreasing energy, gamma rays, cosmic rays, X-rays and...

Cryocoolers

What is a Cryocooler? A mechanism that can extract heat from an object (cooler) and by doing so draw its temperature down below approximately 150 Kelvin (cryo). — (Courtesy Dr. Willy Gully) What is the difference between a Cryocooler and a Cryostat? A cryostat is any device designed to maintain...

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...
