A Quarter-Century Industry Experience Brings About New Company

After 25 years in the high-tech cryogenics field, while employed at Cryogenic Technical Services (CTS) and High Precision Devices (HPD) and working with some of the best scientific minds in the world, Charlie Danaher started Danaher Cryogenics in early 2022 to respond to the ever-increasing demand for elegant, collaborative solutions...

Are We Alone in the Cosmos? Space Dynamics Lab to Help Answer the Question

Utah State University’s Space Dynamics Laboratory (USU SDL) announced in May 2022 that it has delivered a critical subsystem to NASA’s Jet Propulsion Laboratory (JPL) for integration onto the Nancy Grace Roman Space Telescope. The Cryogenic Thermal Subsystem for the Roman Coronagraph Instrument was delivered to JPL at SDL’s facilities...

Turboexpanders Are Key Components to the Energy Transition

With the energy sector looking to decarbonize, the transition away from hydrocarbons is underway, with hydrogen taking center stage in many of the industry’s roadmaps. Georgia-based Chart Industries (NYSE: GTLS) has responded to this interest by bolstering its offering of products and technologies that enable the industry to move away...

Test Chamber for NASA’s New Cosmic Mapmaker Makes Dramatic Entrance

After three years of design and construction, a monthlong boat ride across the Pacific Ocean, and a lift from a 30-ton crane, the customized test chamber for NASA’s upcoming SPHEREx mission has finally reached its destination at Caltech’s Cahill Center for Astronomy and Astrophysics in Pasadena. Set to launch no...

New Microscope Advances Cryo-ET Research

Thermo Fisher Scientific Inc. unveiled the Thermo Scientific Arctis Cryo-Plasma Focused Ion Beam (Cryo-PFIB), a new connected and automated microscope designed to advance the pace of cryo-electron tomography (cryo-ET) research. Cryo-ET makes it possible to study how proteins and other molecules operate together in a cellular context, at resolutions unsurpassed by...

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...
