O”H” What a Feeling, Toyota Introduces Hydrogen Powered Semi

Toyota has announced a new zero-emission hydrogen fuel cell system designed for semi-truck use at the Port of Los Angeles. Dubbed "Project Portal," the proof of concept vehicle was unveiled at a press conference with port officials and representatives from the California Air Resources Board and the California Energy Commission....

European XFEL Commissions Its Particle Accelerator

The European XFEL has successfully commissioned the particle accelerator that will drive its X-ray laser. When fully operational, the research facility will produce up to 27,000 X-ray laser flashes per second, each so short and intense that researchers can make pictures of structures and processes at the atomic level. The...

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...

Helium-3

Helium-3 (3He) is one of the two stable isotopes of helium. The other is the much more common Helium-4 (4He). Neither of these isotopes should be confused with He II, which is the second liquid phase of 4He. He II was discussed in this column in the Spring 2010 edition...

Cryopumping

Cryopumping refers to the use of cryogenic temperatures to produce vacuum in enclosed spaces. More broadly, it can also refer to the removal of gases via cryogenic temperatures from a flow stream or enclosure without necessarily resulting in vacuum pressures. This is an important application of cryogenics and is used...

Thermal Acoustic Oscillations

Thermal Acoustic Oscillations (TAO) are a common event in cryogenic systems that can have significant adverse effects on the performance of the system. TAOs are sustained pressure oscillations that can occur in tubes containing gas, closed at one end (the warm end) that have a very large temperature gradient along...

Food Processing

Cryogenics and Food The industrial gas industry provides a host of products and services related to food. The various gases have useful and sometimes fascinating applications in food industry. “The food industry is not a homogenous industry. The needs of customers processing hamburger vs. poultry vs. strawberries vs. seafood, for...

Primary Standards

Elie K. Track Hypres, Inc. elie@hypres.com http://www.hypres.com/ Primary standards involve the exact definition and realization of units of measurement for various quantities, time, length, mass, voltage, resistance, current, etc. International agreements based on the latest scientific knowledge define those units, and their realizations vary depending on the unit itself. For...

Shrink Fitting

Robin A. Rhodes Cryogenic Institute of New England, Inc. rrhodes@nitrofreeze.com Shrink fitting, (or “compression fitting” as it is sometimes called), is a method used to insert a pin or bushing into a housing or other assembly requiring an extremely tight tolerance fit. It can be used as an alternative to...

Telecommunications

From the Winter 2004 issue of Cold Facts magazine The recent M-Calc IV — 4th Industry Assessment workshop discussing military and commercial applications for low-cost cryocoolers, held in November in San Diego, highlighted progress being made in cryogenics as applied in telecommunications. The reliability and long lifetime of projects now...

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?
