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...

Cold Compressors

A common way to provide cooling below the normal boiling point of helium (4.2K) is to reduce the pressure above the bath of liquid helium, thus also reducing the bath’s equilibrium saturation temperature. For example, to produce a 1.8K bath of liquid helium, the saturation pressure has to be reduced...

Kapitza Conductance

Kapitza conductance refers to the heat transfer between a solid surface and a fluid that covers that surface. Fundamentally, it describes the inherent difficulty in transferring energy from a solid to the fluid covering the solid surface. This phenomenon was first observed by P. L. Kapitza in 1941 while studying...

Thermosyphons

A thermosyphon (or thermosiphon) is a device that transfers heat via natural convection in a fluid. The natural convection is driven by gravity with the colder, denser fluid flowing downhill and the warmer, less dense fluid flowing back up. Thus, thermosyphons connect an object to be cooled with a reservoir...

Wind Tunnels

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...

History of Cryogenics

From the Fall 1999 issue of Cold Facts magazine Millennium Breakthroughs A variety of CSA members give different perspectives on the past millennium: What were the most significant breakthroughs in cryogenics during the past millennium? Prof. R.G. Scurlock, Kryos Technology, scurlock@soton.ac.uk (“Breakthrough” = way through obstacles — Oxford English Dictionary)...

Cryobiology

Andreas Sputtek Past President Society for Cryobiology sputtek@uke.uni-hamburg.de or http://www.sputtek.de/. The word cryobiology (from the Greek words “cryo” = cold, “bios” = life, and “logos” = science) literally signifies the science of life at low temperatures. In practice, this field comprises the study of any biological material or system (e.g.,...

Cryogenic Insulation

James E. Fesmire Cryogenics Test Laboratory NASA Kennedy Space Center james.e.fesmire@nasa.gov Introduction In today’s world, the use of cryogenics and low-temperature refrigeration is taking a more and more significant role. From the food industry, transportation, energy, and medical applications to the Space Shuttle, cryogenic liquids must be stored, handled, and...

An Issue of Pressure and Flow Rate in a Supply Tank

Please help solve this problem: A supply tank requires a vaporizer to generate sufficient pressure to pump stored fluid up into a vehicle or tank. The available head is limited as the tank level falls and it is important to minimize the system pressure drop to maintain the desired flow...

Using MLI on VJ Line Joints or Cryo Storage Tanks

When installing Multi Layer Insulation (MLI) blankets on VJ line joints or cryo storage tanks should they be wrapped and tied down tight or loose? These are usually pre-cut to size. Also should they have an access hole at the point of where the molecular sieve is installed to help...

Separated layers of ice over a pipe

I want to know that why there are different layers of ice over a pipe carrying a cryogenic fluid, each layer separated with clear marks / lines? What do these layers signify?
