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.

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...

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...

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...

Liquefied Natural Gas

Liquefied Natural Gas as it relates to the Field of Cryogenics John W. Bonn VJ Systems, LLC johnbonn@vjsystems-lic.com Today the world is looking for a cleaner fuel and Liquefied Natural Gas (LNG) plays a large part in achieving this goal. LNG in a liquid form is at -162°C (-259°F) and...

An Issue of Pressure and Flow Rate in a Supply Tank

Please help solve this problem: A supply tank requires a vaporizer to generate sufficient pressure to pump stored fluid up into a vehicle or tank. The available head is limited as the tank level falls and it is important to minimize the system pressure drop to maintain the desired flow...

Using MLI on VJ Line Joints or Cryo Storage Tanks

When installing Multi Layer Insulation (MLI) blankets on VJ line joints or cryo storage tanks should they be wrapped and tied down tight or loose? These are usually pre-cut to size. Also should they have an access hole at the point of where the molecular sieve is installed to help...
