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

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...
Thermal shock on steel cylinder when dropped into liquid nitrogen
We are a research team at the University of South Florida, studying the “thermal shock” on a steel cylinder when it is dropped into liquid nitrogen. We want to make sure that the thermocouple does not get influenced by the surrounding LN2. Any advice?
Getter materials to absorb out gassed materials?
Here’s one for the scientists: We would like to sell vacuum insulated pipe for high temperature fluid applications. Are there any good getter materials that we can place in the vacuum space of our VJP to absorb outgassed materials at elevated temperatures?
