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...

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...

I was looking for suppliers of regenerator materials. Can you please provide a list of vendors for: • Lead spheres • Bronze screen discs • Rare earth materials and spheres Thank you in advance for any help you can provide.

Containing ice accumulation while recovering helium

We are implementing a system to recover helium from our Janis ST-500 continuous flow LHe cryostat. The recovery system uses standard 1/4″ plastic tubing, which we connect directly to the cryostat’s exhaust port. The problem with this setup is that the gas is still quite cold as it leaves the...

Looking for some advice regarding cryogenic modeling in ANSYS FEA software

I am looking for some advice regarding cryogenic modeling in ANSYS FEA software. I have been trying to use the Transient Thermal module, in workbench 14.5, to model the cooling of a device in a dilution fridge. I have approximate values for the cooling power of each plate in the...
