JSAP publishes inaugural issue of the JSAP Bulletin

The Japan Society of Applied Physics (JSAP) has published the first issue of the new JSAP Bulletin, a tri-annual online publication designed to highlight JSAP's activities and inspire a global audience engaged in academic and industrial research.

Fermilab Accelerator Division demonstrates Booster Neutrino Beamline operations

After five months of repairing and retooling the Booster Neutrino Beamline (BNB), members of the Accelerator Division at Fermi National Accelerator Laboratory successfully delivered beam to the BNB on June 22. The previous horn, BNB-2, was found to be inoperable in January when it was determined its cooling was no...

Used MRI magnets get a second chance at life in high energy physics experiments

Researchers at the US Department of Energy's Argonne National Laboratory recently acquired two decommissioned magnets from magnetic resonance imaging (MRI) scanners from hospitals in Minnesota and California that will find a new home as proving grounds for instruments used in high energy and nuclear physics experiments. The two new magnets...

Physicist Peter Winter wins DOE Early Career Award

High energy physicist Peter Winter of the US Department of Energy's (DOE) Argonne National Laboratory has received a DOE Early Career Award, a prestigious five-year research grant totaling $2.5 million. The grant will help to fund Winter's contributions to the muon g-2 experiment currently being assembled at Fermi National Accelerator...

NASA issues request for information on Stirling power systems

NASA’s Science Mission Directorate is seeking information on Stirling power systems and technologies that could be developed into a space-based power system that would provide between 100-500 Watts of electricity for future deep space missions. In partnership with the Department of Energy, a Request for Information (RFI) posted on June...

X-ray ptychography, fluorescence microscopy combo sheds new light on trace elements

Using the Advanced Photon Source, a US Department of Energy Office of Science User Facility at Argonne National Laboratory (CSA Corporate Sustaining Member), a team of researchers demonstrated unparalleled sensitivity for measuring the distribution of trace elements in thicker specimens at cryogenic temperatures, in this case at about -260°F. They...

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...

Looking for the thermal conductivity of the high density polyethylene (HDPE) between 1.9 and 10K

I am looking for the thermal conductivity of the high density polyethylene (HDPE) between 1.9 and 10K (or even up to higher temperatures). The best would be to have these data for the HDPE material which sold by the CERN shop, which has a density of 0.95 g/cm3. Pier Paolo...
