New Superconducting Undulators Key to Next-Gen XFELs

Researchers at the US Department of Energy’s Lawrence Berkeley National Laboratory and Argonne National Laboratory (CSA CSM) have collaborated to design, build and test two superconducting undulator devices that could make X-ray lasers more powerful, versatile, compact and durable. In tests, the prototype SCUs successfully produced stronger magnetic fields than...

Sending out an SRF, Fermilab and Northwestern Partner for Applied Superconductivity Center

Northwestern University and the Department of Energy’s Fermi National Accelerator Laboratory (CSA CSM) have established a new research center where scientists will focus on advancing superconductivity, hoping to produce societal gains in the fields of particle physics, solid-state physics, materials science, medicine, energy and environmental sciences. Included are investigations into...

New Form of Matter Is Supersolid

An MIT research team has created a supersolid, a new form of matter that combines both form and viscosity-free flow—properties that most people consider mutually exclusive. The team formed the new material from a Bose-Einstein condensate (BEC), suspending the superfluid gas in an ultrahigh vacuum and then manipulating the sample...

Air Liquide Picks Lydall for ITER Project

Air Liquide advanced Technologies has chosen Lydall Performance Materials to supply insulation for cryogenic lines the company is manufacturing for the ITER fusion machine. Both are CSA Corporate Sustaining Members. ITER engineers use extreme low temperature to cool the superconducting magnets needed to confine and stabilize the machine's fusion reaction....

Air Products and Linde North America Announce Joint Venture, will Build Industrial Gas Plant in Upstate NY

Linde North America has formed a new joint venture with Air Products named East Coast Nitrogen (ECN), through which the companies will build a new 1,100 ton per day world-scale air separation unit and industrial gas liquefier in Glenmont NY. An approximate capital investment of $60 million will be made...

Illini Physicists Develop Superconducting Nanoscale Memory Cell

Researchers at the University of Illinois at Urbana-Champaign have developed a new nanoscale memory cell that provides stable memory at a smaller size than other proposed memory devices and holds tremendous promise for successful integration with superconducting processors.

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...

Cryogenic Treatment of Materials

F.J. Diekman Controlled Thermal Processing, Inc. info@metal-wear.com Cryogenic Processing (also called cryogenic treatment, and incorrectly “cryogenic tempering”) is a process that uses cryogenic temperatures to modify materials to enhance their performance. Cryogenic Processing involves the slow reduction in temperature of the material to at least -300°F (-185°C) and holding the...

Cryogenics in Space

Peter Kittel University of California-Berkeley pkittel@cal.berkeley.edu Space Cryogenics is the application of cryogenics to space missions. These applications fall into two broad areas, supporting space science missions and supporting the space transportation infrastructure. Science applications: The atmosphere is opaque to much of the electro-magnetic spectrum. In space, the absence of...

Thermal shock on steel cylinder when dropped into liquid nitrogen

We are a research team at the University of South Florida, studying the “thermal shock” on a steel cylinder when it is dropped into liquid nitrogen. We want to make sure that the thermocouple does not get influenced by the surrounding LN2. Any advice?

Getter materials to absorb out gassed materials?

Here’s one for the scientists: We would like to sell vacuum insulated pipe for high temperature fluid applications. Are there any good getter materials that we can place in the vacuum space of our VJP to absorb outgassed materials at elevated temperatures?

Data on Carbon Fibres Reinforced Plastic at temperatures between 4 and 300K.

I am looking for data on Carbon Fibres Reinforced Plastic at temperatures between 4 and 300K. I would appreciate it if someone could give me some hints on where to find it.
