Mike Lindgren has been appointed as the head of Fermilab's Particle Physics Division. Lindgren has been a scientist with the lab since 2004, and most recently served as acting head of the division.
Japan’s earthquake brings major science institutions to a standstill
In the wake of the March 11 earthquake that rocked Japan, major science experiments and research institutions are taking stock of the damage to their facilities and dealing with a number of setbacks.
Fermilab’s Alex Romanenko unlocks hidden secrets for improving SRF cavities
Fermilab’s Alex Romanenko recently unlocked secrets hidden beneath the mirror-smooth surface of niobium superconducting radiofrequency (SRF) cavities that may hold the key to the success of future linear colliders. Romanenko’s discovery, which was carried out as part of his doctoral thesis at Cornell University, has earned him “The Particle Accelerator...
UCLA Engineering establishes Endowed Chair in Cryogenics
UCLA Engineering has established the Traugott and Dorothea Frederking Endowed Chair in Cryogenics. The chair will support junior faculty for terms up to five years as they build their careers in areas related to cryogenics.
Lake Shore Cryotronics CEO appointed to PECSEA
Michael Swartz, CEO of Lake Shore Cryotronics, Inc., was appointed to the President's Export Council Subcommittee on Export Administration (PECSEA) by US Commerce Secretary Gary Locke earlier this month.

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...
Magnetic Levitation
From http://www.superconductors.org. Magnetic-levitation is an application where superconductors perform extremely well. Transport vehicles such as trains can be made to “float” on strong superconducting magnets, virtually eliminating friction between the train and its tracks. Not only would conventional electromagnets waste much of the electrical energy as heat, they would have...
Superconductivity
From Superpower website. History of Superconductivity Superconductivity was discovered in 1911 by the Dutch physicist, Heike Kammerlingh Onnes when he was able to liquefy helium by cooling it to 4 Kelvin, or -452°F. This enabled him to cool other materials close to absolute zero and investigate their electrical properties. He...
Medical Applications of Cryogenics
Neutron Therapy Cryogenics is at the heart of nuclear accelerators. Accelerators such as Fermilab’s Tevatron make neutron therapy for cancer possible. From Fermilab Today 4/20/09: Fermilab currently offers neutron therapy. But staff at Fermilab designed and built the proton accelerator used by the nation’s first hospital-based treatment center to use...
Nuclear Physics
Al Zeller National Superconducting Cyclotron Lab (NSCL) at Michigan State University zeller@nscl.msu.edu Cryogenics has a long history in nuclear physics. The technology has its origins in the use of cold traps for maintaining a vacuum, which is required to prevent beam loss and for generating high voltages used in acceleration....
Looking for manufacturers of cryogenic dewars with infrared detectors (long wave)
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?
Manufacturers of cryogenic regenerator lead spheres?
Would you please suggest a few manufacturers that produce cryogenic regenerator lead spheres? The size we need is 0.15mm-0.2mm. I don’t have a lot of ideas for where to go to purchase them.
Assistance with resolving a sealing problem?
We are fabricating piping components for refrigeration service. These components must be leak checked at 15 bar (218 psig). We are using a gas test media that is 25% helium and experiencing difficulty on maintaining a seal on the flanged connections. Do you know anyone or any references that could...
Cryogenic data on leather and nomex
Could anyone please help me out with the following cryogenics data: Leather — mechanical properties at 77 K or lower Nomex — thermal conductivity @ 4 to 50 K I lost the data I had some time ago and although this should be easily accessible, I can’t find any reference...
