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...

TS diagram for helium

Where can I obtain a really big, nice TS diagram for helium ?

Reliability and mounting of electronic substrates at low temperatures

I am currently working on the design of a focal plane assembly to be implemented on a small satellite (4 EMCCD detectors) to be operated at -80°C (which is not really cryogenic and likely still considered boiling hot for most of you :-). As it is passively cooled, the assembly...

Are 3D drawings included in the sale of a cryogenic plant?

I have a question concerning the 3D drawings of a cryogenic plant. The integration of the 3D drawings of a plant with the 3D main model of a new laboratory or a new facility can be a complex work that takes a lot of time. I would like to know...

Looking for a source of LOX impact testing to ASTM D2512

I have been looking for a source of LOX impact testing to ASTM D2512. I am aware of NASA and White Sands, but am looking for a commercial entity doing the work. No luck so far, even calling a lot of the folks on the CSA website. Any referrals will...
