Extreme Cool – Making Liquid Nitrogen in a Deep Underground Clean Lab

SNOLAB is Canada’s deep underground research laboratory, located two kilometers underground in Vale’s Creighton mine near Sudbury, Ontario, Canada. SNOLAB is a unique facility, providing a low background environment designed for scientific research and operates a 5,000m2 underground campus as a class-2000 clean lab. While the science program is focused...

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...

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...

Food Processing

Cryogenics and Food The industrial gas industry provides a host of products and services related to food. The various gases have useful and sometimes fascinating applications in food industry. “The food industry is not a homogenous industry. The needs of customers processing hamburger vs. poultry vs. strawberries vs. seafood, for...

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...
