NOAA Reports Cooling Failure aboard GOES-17

The National Oceanic and Atmospheric Administration has reported a performance issue with the cooling system aboard GOES-17, a multibillion-dollar weather satellite launched in March. NOAA engineers encountered the issue during commissioning of the satellite’s Advanced Baseline Imager instrument.

DOE Funds International Cryogenic Dark Matter Experiment, Construction Underway at Canada’s SNOLAB

The US Department of Energy Office of Science and the National Science Foundation have approved funding and the start of construction for the SuperCDMS SNOLAB experiment, that will begin in the early 2020s to hunt for light dark matter particles. DOE’s Fermi National Accelerator Laboratory (CSA CSM) will play a...

Lake Shore Cryotronics Celebrating 50 Years

Lake Shore Cryotronics (CSA CSM) is celebrating 50 years in business this year, and in May it recognized the people who helped it become a worldwide leader in precision measurement over a wide range of temperature and magnetic field conditions.

Young Professionals 2018: The Next Generation in Cryogenics Part 2

Young Professionals 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 Summer 2006 issue, the feature has presented many young persons whom we are proud to see...

A Brief Report on the First Cooldown of SPIRAL2

Over the last 10 years, a multidisciplinary team from institutes around the world has worked to design, fabricate and assemble SPIRAL2, a new generation heavy ion superconducting linear accelerator (LINAC) at the Grand Accélérateur National d’Ions Lourds (GANIL) facility in Caen, France.

SSRL X-ray Uncovers Hidden Ancient Text

More than 1,600 scientists from all over the world use the Stanford Synchrotron Radiation Lightsourse (SSRL) at SLAC National Accelerator Laboratory each year for research that spurs advances in medicine, energy production, environmental cleanup, nanotechnology and new materials. And now, a multidisciplinary team has used the machine’s acceleratordriven X-rays to...

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...

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...
