JSC’s historic vacuum chamber ready to test Hubble’s successor

An upgrade eight years in the making is complete, and Johnson Space Center is now home to the only vacuum chamber in the world that is large enough and cold enough to provide a space-like environment for the James Webb Space Telescope.

Fermilab physicists rework plans for LBNE

On August 28, officials from Fermilab presented their revised plan for the first stage of the Long-Baseline Neutrino Experiment (LBNE) to a federal advisory panel.

X-rays reveal spin waves in two-dimensional high-temperature superconductors

Physicists working at Brookhaven National Laboratory and Switzerland’s Paul Scherrer Institute have revealed key quantum characteristics of high-temperature superconductors, demonstrating new experimental methods and breaking fundamental ground on these mysterious materials.

Larsen & Toubro Ltd to manufacture ITER Cryostat

The ITER cryostat will be the largest high-vacuum pressure chamber ever built. On August 17, a contract for the manufacturing of the 3,800-ton steel structure was signed with the Indian company Larsen & Toubro (L&T) Ltd.

OSHA cites Plains Gas Solutions for violations after explosion and fire

The US Department of Labor's Occupational Safety and Health Administration has cited Plains Gas Solutions LLC in Eunice, Louisiana, for one willful and seven serious violations involving OSHA's process safety management standards following an explosion and fire that severely burned a worker.

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...

Bose-Einstein Condensate

A Bose-Einstein condensate, first proposed in 1925 by Albert Einstein based on work done by Satyendra Nath Bose (the same Bose from whom the term boson is derived), is a super-cold state of matter in which almost all of the individual atoms have “condensed” down to the lowest possible quantum...

Cold Technology for Pest Control

While it does not reach temperatures cold enough to be called cryogenic, carbon dioxide snow is at the heart of a new way of dealing with unwanted pests. It utilizes a quick freezing process that takes advantage of the properties of carbon dioxide snow and has a number of benefits...

Cryogenic Finishing

Definition or max temp which defines “cryogenic”?

Please help me with a definition: I am calculating material and fabrication costs for a quote for a hydrocarbon meter station.

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.
