Goddard Goings: When NASA Went SHOOTING Into Orbit

The ’80s have been thrust back into our collective conscious! Hits such as Tracy Chapman’s “Fast Car” and “Running up that Hill” by Kate Bush have been introduced to a new generation by an incredibly popular cover of the first song and the repetitious use of the second in a...

Quantum Design Explores Quantum Frontiers with Precision Measurements

Since 1982, Quantum Design has been providing lab-ready scientific instruments to colleges, universities, government and corporate laboratories around the world. Instruments include the DynaCool® Physical Property Measurement System (PPMS), the MPMS3® SQUID Magnetometer and VersaLab® Physics Education System. The OptiCool® is a large volume, low vibration, low temperature and high...

Under Pressure: Harvard Scientists Break Through Precise Measurement with New Tool

Hydrogen (like many of us) acts weird under pressure. Theory predicts that when crushed by the weight of more than a million times Earth’s atmosphere, this light, abundant, normally gaseous element first becomes a metal and then, even more strangely, a superconductor – a material that conducts electricity with no...

The Next Generation in Cryogenics and Superconductivity

This feature introduces outstanding young professionals (under 40 years of age) who are doing interesting things in cryogenics and superconductivity and who show promise of making a difference in their fields. Debuted in the 2006 issue, the feature has presented many young persons whom we are proud to see have indeed lived...

Enhancing Fusion Reactor Control Through Combined Plasma Management Techniques

The team’s latest simulations, discussed in their recent publication in Nuclear Fusion, mark the first instance where ECCD and RMP have been used together experimentally. “We are exploring new frontiers with this approach, enhancing our control over plasma behavior,” commented Qiming Hu, a PPPL staff research physicist and the paper’s...

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

The following 3 articles discuss the uses and procedures of various type of cryogenic finishing. 1) By Robin A. Rhodes, Cryogenic Institute of New England, Inc. rrhodes@nitrofreeze.com Cryogenic Deflashing is employed to remove undesired residual mold flash that remains on molded parts after they are removed or ejected from the...

Power usage: cryogenic systems vs. regular refrigerators

A recent project highlighted to me that closed cycle cryogenic cooling systems use far more electrical power to reduce temperatures by a few watts than regular refrigerators. I am sure it must be something to do with the extra difficulty of removing the heat from the liquid nitrogen or similar...

Redundancy strategies for mechanical -80C freezers

I was wondering what kind of redundancy strategies are people using for their mechanical -80C freezers? I am aware of the following. Please add if you are doing something different. 1) 1 Backup freezer for every 10 freezers – Empty and maintained at -80C at all times 2) Backup C02...

Safety guidelines for handling cryo vessels of nitrogen

I am looking for any safety guidelines for handling cryogenic vessels of nitrogen indoors and outdoors. I am especially interested in recommendations for area monitors to detect leaks, flow detection devices, etc.

Method to move components in a cryogenic environment

Does anyone know of a method with which to reliably move components in a cryogenic environment? We are interested in moving detectors in a cryogenically cooled (2K) vacuum chamber, which is contained within a larger cryostat/isolation vacuum with thermal shields. As the desired horizontal or vertical displacement is between 10...
