KEK Publishes the International Working Group’s Recommendations for International Linear Collider

KEK has received the International Working Group’s report of recommendations regarding the International Linear Collider (ILC) project and published a document, “Recommendations on ILC Project Implementation," outlining the suggestions. The report calls for cost-sharing programs for the civil engineering projects, accelerator components, conventional facilities construction and operating costs. It goes...

World’s First Hydrogen Powered Boat Docks in London

The world's first hydrogen powered boat has docked in London, the last stop of its European tour. The 30-meter Energy Observer acts as a “floating lab” for testing green maritime technology. It harnesses electricity from three renewable energies¬¬¬–hydrogen, solar and wind–to propel the boat and charge its batteries. Using this...

“Orange” You Excited for SLAC’s New X-Ray Laser?

See upgrades to SLAC National Accelerator Laboratory’s X-ray laser, including some of the 37 cryomodules to be completed, in a collection of photos showcasing its trademark orange styling, and learn more about the experiments it will enable.

SOFIA Soars to Observe the Universe

SOFIA, the Stratospheric Observatory for Infrared Astronomy, is a unique plane-based observatory housed inside a 747 aircraft. A joint project between NASA, Universities Space Research Association, and the German Aerospace Center-DLR since 1997, it takes advantage of the stratosphere to eliminate the absorbing effect atmospheric water has on infrared observations....

Cryogenics Takes Center Stage for PIP-II at Fermi National Accelerator Laboratory

Construction of the Proton Improvement Plan II (PIP-II) is underway at Fermi National Laboratory (CSA CSM) in Batavia IL. Since the groundbreaking ceremony on March 15, the laboratory team has been preparing for the beam that will contribute to international high energy physics research experiments. The superconducting radio-frequency (SRF)-powered linear...

Cryoablation of Breast Cancer Cells Offers Non-Invasive Option

Breast cancer patients at Cedars-Sinai hospital in Los Angeles have a promising cryogenic option to significant intrusive surgeries thanks to cryoablation. Dr. Peter Julien, chief of thoracic imaging and tumor ablation at the S. Mark Taper Foundation Imaging Center at Cedars-Sinai, has been conducting a study using cryoablation to treat...

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...

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...

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...

Seeking alloy that keeps elastic property down to 10K

I am looking for a metal (alloy) that supports high temperatures (at least 1600K) and keeps its elastic property at low temperatures down to 10K. Rhenium is a good one because it does not become brittle. But it is quite expensive. Pure tungsten and molybdenum enter in the brittle regime...

Searching for a freezer that does not need electricity

I’m student of University of Barcelona. We do technical cryogenic research and we are searching for a cryogenic portable freezer that does not need electricity. We can’t find any company that offers something like this. The product we are looking for is the typical portable freezer for food or drinks...
