Innovative Accelerator Achieves Full Energy Recovery

An innovative particle accelerator designed and built by scientists from the US Department of Energy’s Brookhaven National Laboratory and Cornell University has achieved a significant milestone that could greatly enhance the efficiency of future particle accelerators. After sending a particle beam for one pass through the accelerator, machine components recovered...

Hydrogen-Powered Bicycles Offer New Electromobility Concept

Pragma Industries has received an order for 1,000 bicycles from Chilean president Sebastian Pinera after 200 hydrogen bicycles were made available to journalists and world leaders at the recent G7 summit in Biarritz. The company’s founder, Pierre Forté, envisions that the bicycles will have an environmental impact in developing countries.

Particle Accelerators Drive Decades of Discoveries at Berkeley Lab and Beyond

Accelerators have been at the heart of the Department of Energy’s Lawrence Berkeley National Laboratory (Berkeley Lab) since its inception in 1931, and are still a driving force in the laboratory’s mission and its R&D program. Accelerator R&D and experiments at the lab—and lab scientists’ participation in experiments at other...

Liquid Nitrogen as a Hair Solution?

Celebrity hairstylist Savio John Perreira is using cryogenics to treat hair at his Mumbai salon with the Cryo Detox hair treatment by Kerasol. The process includes a step where liquid nitrogen is sprayed on the hair strands. What could go wrong?

28th SCW Connects International Cryogenics Community

107 scientists, researchers and students attended CSA’s 28th Space Cryogenics Workshop held July 18 at the Heritage Hotel and Conference Center in Southbury CT. Attendees had the opportunity to share ideas in the form of back-to-back oral presentations with poster session breaks. The first day began with lectures on upcoming...

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...

Food Processing

Cryogenics and Food The industrial gas industry provides a host of products and services related to food. The various gases have useful and sometimes fascinating applications in food industry. “The food industry is not a homogenous industry. The needs of customers processing hamburger vs. poultry vs. strawberries vs. seafood, for...

Primary Standards

Elie K. Track Hypres, Inc. elie@hypres.com http://www.hypres.com/ Primary standards involve the exact definition and realization of units of measurement for various quantities, time, length, mass, voltage, resistance, current, etc. International agreements based on the latest scientific knowledge define those units, and their realizations vary depending on the unit itself. For...

Shrink Fitting

Robin A. Rhodes Cryogenic Institute of New England, Inc. rrhodes@nitrofreeze.com Shrink fitting, (or “compression fitting” as it is sometimes called), is a method used to insert a pin or bushing into a housing or other assembly requiring an extremely tight tolerance fit. It can be used as an alternative to...

Telecommunications

From the Winter 2004 issue of Cold Facts magazine The recent M-Calc IV — 4th Industry Assessment workshop discussing military and commercial applications for low-cost cryocoolers, held in November in San Diego, highlighted progress being made in cryogenics as applied in telecommunications. The reliability and long lifetime of projects now...
