Particle Accelerator Magnet Sets Record Using High Temperature Superconductor

Cost- and energy-efficient rapid cycling magnets for particle accelerators are critical for particle physics research. Their performance determines how frequently a circular particle accelerator can receive a bunch of particles, propel them to higher energy, send them to an experiment or target station, and then repeat all over again. A...

The Second Quantum Revolution

For physicists trying to harness the power of electricity, no tool was more important than the vacuum tube. This lightbulb-like device controlled the flow of electricity and could amplify signals. In the early 20th century, vacuum tubes were used in radios, televisions and long-distance telephone networks. But vacuum tubes had...

NSF Grant Funds New 40T Superconducting Magnet Design

A new $15.8 million grant from the National Science Foundation (NSF) will produce a detailed design for the world’s most powerful superconducting magnet at the Florida State University-headquartered National High Magnetic Field Laboratory (CSA CSM). While the National MagLab is already home to more than a dozen world-record magnets used...

Webb Space Telescope Will “Revolutionize Our Understanding” of the Universe

On December 25, the largest and most powerful space telescope ever constructed by NASA was successfully launched from Earth. With unprecedented technology, the James Webb Space Telescope (JWST) will peer both near and far, from the planets and bodies in our solar system to the deepest reaches of space, where the...

CryoHiVac Investigates Cryogenic Market, Affordability from Earth to Space

Today’s time-sensitive market needs revolutionization of traditional costly technologies. The cryogenic and electronic market development and utilization started from 1970 for commercial applications, and both are fast-growing technologies. There has been significant advancement of electronic products. Nowadays, a small smartphone has much more data storage and processing power capability than...

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...

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...
