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...

Two-Phase Flows

Two-phase flows are those flows in which there is a mixture of two physical states (solid, liquid or vapor). In cryogenic applications, such flows are almost always a mixture of a cryogenic liquid along with its corresponding vapor. A mixture of liquid helium and helium vapor would be a typical...

Supercritical Fluids

A supercritical fluid is defined as a substance whose temperature and pressure exceed those of its critical point. Every pure substance has a critical point that is defined in thermodynamic space by a critical temperature and a corresponding critical pressure. For example, the critical point for helium has a critical...

Brayton Cycle

The Brayton cycle is one of the many thermodynamic cycles used to generate cooling at cryogenic temperatures. Strictly speaking, when referring to cooling we should call this the reverse Brayton cycle as the original Brayton cycle describes the process of power generation or propulsion via a gas turbine. In many...

Magnetic Levitation

From http://www.superconductors.org. Magnetic-levitation is an application where superconductors perform extremely well. Transport vehicles such as trains can be made to “float” on strong superconducting magnets, virtually eliminating friction between the train and its tracks. Not only would conventional electromagnets waste much of the electrical energy as heat, they would have...

Superconductivity

From Superpower website. History of Superconductivity Superconductivity was discovered in 1911 by the Dutch physicist, Heike Kammerlingh Onnes when he was able to liquefy helium by cooling it to 4 Kelvin, or -452°F. This enabled him to cool other materials close to absolute zero and investigate their electrical properties. He...

Medical Applications of Cryogenics

Neutron Therapy Cryogenics is at the heart of nuclear accelerators. Accelerators such as Fermilab’s Tevatron make neutron therapy for cancer possible. From Fermilab Today 4/20/09: Fermilab currently offers neutron therapy. But staff at Fermilab designed and built the proton accelerator used by the nation’s first hospital-based treatment center to use...

Nuclear Physics

Al Zeller National Superconducting Cyclotron Lab (NSCL) at Michigan State University zeller@nscl.msu.edu Cryogenics has a long history in nuclear physics. The technology has its origins in the use of cold traps for maintaining a vacuum, which is required to prevent beam loss and for generating high voltages used in acceleration....

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...
