Congratulations!  Iqra Azam Vera Hansper Jennifer Hennis Tamanna Joshi Nora Juhasz Susan Magi Kayla Rajsky Tara...

BS&B Safety Systems Accelerates Service to OEMs

OEMs in virtually every market, from aerospace and automotive to refrigeration and fire protection, rely on rupture disk devices for pressure relief and pressure release of gases and liquids. The challenge of time faces all product designers; how do we get a custom solution in an acceptable timeframe? Now, at least...

The Cryomech PT205: A Compact Cryocooler with a Wide Range of Applications

In today’s rapidly evolving technological landscape, the demand for efficient and compact cryocoolers is more critical than ever. A wide range of applications increasingly require high performance cooling systems that can seamlessly integrate into limited spaces. Smaller cryocoolers prove invaluable in these contexts, offering the precision and reliability necessary to...

CO2Meter’s Critical Gas Safety Solution

CO2Meter has long been recognized for its remote oxygen depletion safety alarm, which warns staff before they enter areas with dangerously low oxygen levels caused by pressurized gas leaks. Pressurizing a gas in a tank or cylinder provides a convenient way to transport and store it. Flower shops use helium cylinders...

Jefferson Lab Dedicates Niobium-Tin Particle Accelerator Prototype

More than 30 of the world’s most advanced particle accelerators rely on one technology: superconducting radio-frequency (SRF). This technology, typically powered by pure niobium metal, has seen recent advancements with the introduction of niobium-tin alloys, which promise greater efficiency. The US Department of Energy’s (DOE) Thomas Jefferson National Accelerator Facility...

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...

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?
