Richard Hitt, President and CEO, Hypres Inc., and Dr. Elie Track, PhD, Senior Partner, discuss new progress in the use of Superconducting Radio Frequency (SC RF) techniques in telecommunications.
Professors S. Y. Lee and Paul Sokol of the Indiana University Center for Exploration of Energy and Matter (IUCEEM) are currently leading the design effort of a multipurpose electron accelerator called the Alpha Project (Advanced Electron-Photon Facility), which will be operated under a joint collaboration between Crane Naval Surface Warfare...
GE Global Research has been awarded a four-year, $3.27 million award from the National Institutes of Health (NIH) for new magnet technology that will cut back on the costs and inconveniences of current MRI systems.
From http://www.bnl.gov: An international team of scientists studying high-energy collisions of gold ions at the Relativistic Heavy Ion Collider (RHIC), a 2.4-mile-circumference particle accelerator located at the U.S. Department of Energy’s (DOE) Brookhaven National Laboratory, has published evidence of the most massive antinucleus discovered to date.
In the Winter 2010 issue of Cold Facts, an article was featured entitled "Hypres: Progress in SC RF for Telecommunications." The article mentions that Hypres has developed a figure of merit (FoM) that allows them to compare cryocoolers with different stages for their applications.
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 (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,...
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...
Elie K. Track Hypres, Inc. elie@hypres.comhttp://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...
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...
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...
Dr. Robert Kilgore The development of the cryogenic wind tunnel is one of many significant breakthroughs in both cryogenics and wind-tunnel technology made during the past millennium. Interest in the development of high-speed commercial and military aircraft resulted in a review of problems of flow simulation in transonic wind tunnels...
I’m on the hunt for a material/gel/epoxy that will transfer the cold temperature of a cryo-box to a test article. The cryo-box is curved and the test article is at the same curvature. I’m looking for something to put between them to make the surface of the test article as...
I’m seeking a consultant with experience in the manufacture of brazed aluminum heat exchangers for cryogenic applications. Is there anyone you could recommend to me?
We are looking for manufacturers of cryogenic dewars with infrared detectors (long wave). We need these dewars for repairing infrared systems (thermographic systems) and we cannot find such glass dewars. Do you know any manufacturers’ addresses?
