CERN Successfully Tests Cooler Way to Transport Electricity

A 60-meter-long line has been developed for CERN’s future accelerator, the High-Luminosity LHC, which is due to come into operation in 2026. Tests began last year and the line has transported 40,000 amps, 20 times more than what is possible at room temperature with ordinary copper cables of a similar...

Cryogenics, Superconductivity Enabled Historic Black Hole Photograph

In April, the Event Horizon Telescope captured the first ever photo of a black hole. Superconducting submillimeter detectors, developed by engineers and astronomers at the University of Virginia and the National Radio Astronomy Observatory in Charlottesville, helped make visible what once was only black. These devices were responsible for capturing...

Cryo-EM Imaging Enables First Snapshots of Trapped CO2 Molecules

Scientists have taken the first images of carbon dioxide molecules within a molecular cage using a new twist on cryo-EM imaging. The development came in mid-June and reveals what’s going on inside MOFs, highly porous nanoparticles with big potential for storing fuel, separating gases and removing carbon dioxide from the...

Research Group Sets New Temperature Record For Superconductivity

An international team of scientists has built a superconductor that functions at 250 K, nearly 50 °C (84.6 °F) hotter than the previous record high for superconductivity—and it puts the “holy grail” of energy transmission almost within reach. In a study published in Nature, scientists describe their new material, lanthanum...

Helium II

Helium II (He II) refers to the second liquid phase of the most abundant helium isotope (4He). Helium II is also referred to as superfluid helium. Helium II occurs once the temperature of the liquid helium drops below 2.17K. The phase transition between the first liquid phase of Helium (referred...

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...
