ICHEP Publishes 2016 Proceedings

Professor Young-Kee Kim, chair of ICHEP 2016 and professor of physics at the University of Chicago, has announced that proceedings from the high energy physics conference have been published online. The proceedings are organized by session topic and include full PDFs from presenters and research teams.

Microsoft and Rambus Extend Cryogenic Memory Collaboration

Microsoft and Rambus Inc. have expanded a research collaboration begun in 2015 to develop prototype systems that optimize computer memory performance at cryogenic temperatures. The new agreement extends joint efforts to enhance memory capabilities, reduce energy consumption and improve overall system performance.

GOES-S Undergoes Thermal Vacuum Testing

In March, engineers at Lockheed Martin Space Systems lifted NOAA's Geostationary Operational Environmental Satellite-S (GOES-S) into a thermal vacuum chamber to begin testing its ability to function in the cold void of space at its orbit 22,300 miles above the Earth. To simulate the environment of space, researchers removed air...

Hybrid Airships to Transfer Helium from Tanzania

Helium One, a company that holds a prospecting license for recently discovered helium deposits in Tanzania, intends to use Lockheed Martin's LMH-1 hybrid airships to transport the gas out of the country. The company's license includes three project areas in Tanzania, encompassing more than 4,500 km² of land with helium...

Air Products Expands Operations in South China

Air Products has opened a cryogenic air separation plant in the Guangdong Province of South China. The facility will produce both gaseous oxygen and nitrogen in a modular space that allows for easier field installation and requires less land, according to the company.

LArIAT Upgrade Tests DUNE Design

Scientists from the LArIAT experiment at Fermi National Accelerator Laboratory have begun a proof-of-concept test for the planned Deep Underground Neutrino Experiment (DUNE). The researchers studying what will happen if the space between detection wires inside the future DUNE detectors is increased from three millimeters to five, a design that...

Stability

Stability refers to the ability of a device employing superconductors to remain in its superconducting state after part of the superconductor transitions back to its normal conducting state due to a disturbance. While the concept can apply to many superconducting devices—transmission lines, generators, motors, etc.—it is most commonly considered in...

Cable-in-Conduit Conductors

Cable-in-Conduit Conductors (CICC) are a common form of superconducting cable used in large-scale applications. There are several varieties of CICCs, but they all consist of many small, stabilized superconducting wires contained within a conduit through which a coolant (typically supercritical He II) flows. Figure 1 shows the cross section of...

Bayonet Coupling

A bayonet coupling is a demountable joint that allows for quick and easy connection and disconnection of cryogenic components, including transfer lines, cryostats, liquefiers and refrigerators. Bayonets provide a number of advantages, chief among them the ability to connect and disconnect the bayonets while components they connect are still at...

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...
