New Report Buffers Possibility for Molecular Level Data Storage

New research from the University of Manchester (UK) suggests that storing data with a class of molecules known as single-molecule magnets is more feasible than previously thought. The result, published in Nature, shows that magnetic hysteresis, a memory effect that is a prerequisite of any data storage, is possible in...

Brooks Automation Expands Stored Sample Monitoring

Brooks Automation, Inc. (CSA CSM) has acquired FreezerPro® and other assets from RURO, Inc., a Maryland-based developer of computer software for research, biotechnological, pharmaceutical, healthcare and government laboratories. The software enables web-based access to information on stored samples from any location on any device.

EASITrain to Hire, Fund PhD Candidates in Superconductivity and Related Fields

CERN has announced its European Advanced Superconductivity Innovation and Training project (EASITrain), a four-year initiative that brings together leading research institutes and industrial partners to train the next generation of researchers. It will cover the development of 15 Early Stage Researchers (ESRs) on projects related to superconducting wires, superconducting thin...

Electronic Symmetry Breaking Common in Superconducting Materials in High Magnetic Fields

Researchers from the Los Alamos National Laboratory report that the phenomenon of electronic symmetry breaking is common in superconducting materials in high magnetic fields. Using transport measurements near the field-tuned quantum critical point of CeRhIn5 at 50 Tesla, the researchers observed a fluctuating nematic-like state in which the material’s electrons...

UA Researchers to Design New Cryogenic Focal Plane Arrays

The American Institute for Manufacturing Integrated Photonics (AIM Photonics), a public-private partnership advancing the nation’s photonics manufacturing capabilities, has chosen a University of Arizona research team to design, fabricate and test new PIC-based datalinks for cryogenic focal plane array (FPA) readout. The project, according to AIM Photonics, has the potential...

SQUID Detector Reaches New Sensitivity Levels

Investigators at the University of Colorado, Boulder, and the National Institute of Standards and Technology (NIST) have developed a new sensor-array-based instrument that offers ultralow noise detection of small amounts of energy for a number of applications. The new device permits the collection of data from many more detectors than...

Helium-3

Helium-3 (3He) is one of the two stable isotopes of helium. The other is the much more common Helium-4 (4He). Neither of these isotopes should be confused with He II, which is the second liquid phase of 4He. He II was discussed in this column in the Spring 2010 edition...

Cryopumping

Cryopumping refers to the use of cryogenic temperatures to produce vacuum in enclosed spaces. More broadly, it can also refer to the removal of gases via cryogenic temperatures from a flow stream or enclosure without necessarily resulting in vacuum pressures. This is an important application of cryogenics and is used...

Thermal Acoustic Oscillations

Thermal Acoustic Oscillations (TAO) are a common event in cryogenic systems that can have significant adverse effects on the performance of the system. TAOs are sustained pressure oscillations that can occur in tubes containing gas, closed at one end (the warm end) that have a very large temperature gradient along...

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...

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...

Separated layers of ice over a pipe

I want to know that why there are different layers of ice over a pipe carrying a cryogenic fluid, each layer separated with clear marks / lines? What do these layers signify?
