APS Joins SCOAP3 Consortium

CERN, the European Organization for Nuclear Research, and the American Physical Society (APS) have entered into an agreement through SCOAP3 to provide open access to high-energy physics articles published in APS journals. The partnership, which begins in January 2018, covers articles from Physical Review C, Physical Review D and Physical...

NCIS Bungles Investigation, Conflates Cryogenics and Cryonics

A recent episode NCIS, a popular CBS police procedural, featured a villain who killed his victims with liquid nitrogen, interring them alive inside a homemade cryonics chamber. During the big reveal, the NCIS writers conflate cryonics with cryogenics, using one of the show's trope scientific experts to present the latter...

CSA Board Member Joins Superconductivity Center at FSU

Florida State University has hired Lance Cooley, CSA board member and a scientist at the Fermi National Accelerator Laboratory (CSA CSM), to join the Applied Superconductivity Center (ASC) at the FSU-based National High Magnetic Field Laboratory. He will also have a faculty appointment in the Department of Mechanical Engineering at...

Physicists Observe Negative Mass in Bose-Einstein Condensate

Washington State University physicists have created a fluid with negative mass. Push it, and unlike every physical object in the known world, it doesn’t accelerate in the direction it was pushed. It accelerates backward. Led by Peter Engels, WSU professor of physics and astronomy, the researchers generated the conditions for...

O”H” What a Feeling, Toyota Introduces Hydrogen Powered Semi

Toyota has announced a new zero-emission hydrogen fuel cell system designed for semi-truck use at the Port of Los Angeles. Dubbed "Project Portal," the proof of concept vehicle was unveiled at a press conference with port officials and representatives from the California Air Resources Board and the California Energy Commission....

European XFEL Commissions Its Particle Accelerator

The European XFEL has successfully commissioned the particle accelerator that will drive its X-ray laser. When fully operational, the research facility will produce up to 27,000 X-ray laser flashes per second, each so short and intense that researchers can make pictures of structures and processes at the atomic level. The...

Cold Compressors

A common way to provide cooling below the normal boiling point of helium (4.2K) is to reduce the pressure above the bath of liquid helium, thus also reducing the bath’s equilibrium saturation temperature. For example, to produce a 1.8K bath of liquid helium, the saturation pressure has to be reduced...

Kapitza Conductance

Kapitza conductance refers to the heat transfer between a solid surface and a fluid that covers that surface. Fundamentally, it describes the inherent difficulty in transferring energy from a solid to the fluid covering the solid surface. This phenomenon was first observed by P. L. Kapitza in 1941 while studying...

Thermosyphons

A thermosyphon (or thermosiphon) is a device that transfers heat via natural convection in a fluid. The natural convection is driven by gravity with the colder, denser fluid flowing downhill and the warmer, less dense fluid flowing back up. Thus, thermosyphons connect an object to be cooled with a reservoir...

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...
