Transformative ‘Green’ Accelerator Achieves World’s First 8-pass Full Energy Recovery

Scientists from Cornell University and the US Department of Energy’s (DOE) Brookhaven National Laboratory (BNL) have successfully demonstrated the world’s first capture and reuse of energy in a multi turn particle accelerator, where electrons are accelerated and decelerated in multiple stages and transported at different energies through a single beamline....

The Future of Particle Accelerators May Be Autonomous

Operators at the Linac Coherent Light Source (LCLS) particle accelerator, part of SLAC National Laboratory at Stanford University in California, looked into how they were spending their time managing the machine. They tracked the hours they spent on tasks like investigating problems and orchestrating new configurations of the particle beam...

60 Years of DESY: From Hamburg Particle Accelerator to Global Research Center

For the past 60 years, fundamental research has been carried out at the Deutsches Elektronen-Synchrotron (DESY) in Hamburg-Bahrenfeld. In those 60 years, DESY has become a world leader in accelerator technology, structure research, particle physics and astroparticle physics. DESY has developed pioneering technologies, which have been used by scientists from...

Jefferson Lab to be Major Partner in Brookhaven Electron Ion Collider Project

The Department of Energy (DOE) announced that it has taken the next step toward the construction of an Electron Ion Collider (EIC) in the United States. DOE announced that the collider will be sited at DOE’s Brookhaven National Laboratory in Upton NY. In addition, DOE’s Thomas Jefferson National Accelerator Facility...

The Pocket-Sized Particle Accelerator

The accelerator-on-a-chip is just a prototype, but its design and fabrication techniques can be scaled up to deliver particle beams accelerated enough to perform cutting-edge experiments that don’t require the power of a massive accelerator. By placing these chips in a series, researchers from SLAC National Laboratory and Stanford University...

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...

Consultant knowledgeable in LNG

My company is seeking a consultant who is knowledgeable in LNG. It is a project located overseas, and involves a refinery and heat exchangers. Can anyone provide me with a reference?

Source for small gas liquefier/cryocooler?

I would like to acquire a used gas liquefier/cryocooler for use in my non-profit project to build a high-performance natural gas (methane) powered car. I am interested in liquefying piped natural gas (methane) into LNG (about 120K or -154 degrees).
