Western Power Distribution has integrated two 12 kV superconducting fault current limiters (sFCL) from Nexans Deutschland GmbH (CSA CSM) into the Birmingham UK power grid. The installation is part of FlexDGrid, a £17M project that aims to both reduce power cuts and carbon emissions and to increase the capacity of existing networks to facilitate the distribution of renewable energy in Birmingham. Nexans' technology opens up new ways of designing distribution grids, such as coupling busbars to maintain a reliable power supply during maintenance, and therein helps achieve FlexDGrid objectives by enabling higher power feed-in from distributed or renewable electricity sources.
NASA researchers have completed cryogenic testing on the science instruments module for the James Webb Space Telescope (JWST). The module contains JWST's science cameras and spectrographs, and had been undergoing four months of monitoring inside a giant thermal vacuum chamber called the Space Environment Simulator (SES) at NASA's Goddard Space Flight Center in Greenbelt MD. The 40-foot-tall, 27-foot-diameter cylindrical chamber duplicates the extreme temperatures and vacuum of space, eliminating almost all of the air with vacuum pumps and drops the temperature using liquid nitrogen and gaseous helium.
On a sun-drenched hill in Southern California's San Gabriel Mountains, researchers at NASA's Jet Propulsion Laboratory in Pasadena are making progress on an experimental facility that could create the coldest known place in the universe.

The research, which may hasten the development of quantum computers, is available in the journal Nature.
UPS has launched its Temperature True® Cryo system in Europe, providing healthcare customers there access to end-to-end product protection and the capability to ship parcels in a cryogenic environment. The system uses cryogenic containers from Cryoport, a manufacturer of custom built liquid nitrogen dry vapor shippers, to keep products frozen at -150°C for 10 days while in transit or storage.
Scientists at the University of Nottingham have taken a major step towards providing a much clearer picture of lung disease thanks to new scanning technology developed at its Sir Peter Mansfield Imaging Center. The new process makes the spaces inside lungs show up on a magnetic resonance imaging (MRI) scan using specially treated krypton gas as an inhalable contrast agent. Researchers hope the new process will eventually allow doctors to virtually see inside the lungs of patients.
The Asia-Pacific High Energy Physics Panel (AsiaHEP) and the Asian Committee for Future Accelerators (ACFA) have issued a joint statement urging a redoubled international effort to realize the International Linear Collider (ILC) at KEK, Japan's High Energy Accelerator Research Organization. The joint announcement follows a similar one made by the International Committee for Future Accelerators (ICFA) in February, when members of the organization held a press conference in Tokyo.
Princeton University's Plasma Physics Laboratory (PPPL) is readying a facility to detect Big Bang neutrinos by capturing them in tritium, a radioactive isotope of hydrogen. The state-of-the-art project is named PTOLEMY, both as an homage to the second century Greek astronomer and as an acronym for Princeton Tritium Observatory for Light, Early-universe Massive-neutrino Yield. PTOLEMY consists of a pair of superconducting magnets joined to opposite ends of a five-foot vacuum chamber, with the second magnet connected to a calorimeter that measures electron energy.
The Department of Energy (DOE) on March 11 announced $25 million in funding aimed at advancing technologies for energy-efficient electric motors through applied R&D.

Most cryogenic refrigeration systems, both large scale systems and cryocoolers, use helium as a working fluid. There are a number of advantages to helium, not the least of which is that helium remains a fluid down to the lowest achievable temperatures. In order to freeze helium, pressures of over 20 bar need to be applied … Continue reading Mixed Refrigerant Cycles
Over 150 physicists from around the world collided at The University of Texas at Arlington in early January to further collaboration on DUNE, the Deep Underground Neutrino Experiment. The international project, scheduled for completion in the early 2020s, will shoot a neutrino beam from Fermi National Accelerator Laboratory (CSA CSM) in Illinois towards four 10-kiloton liquid argon detectors staged some 4,800 feet below ground at the Sanford Underground Research Facility in South Dakota. The goal of DUNE is to better understand how the universe is put together, and its success hinges on perfecting a novel membrane cryostat to hold both the liquid argon and the cold electronics that will live and function for some 30 years inside it at 88K.
CERN has a long history in superconducting radio frequency (SRF) technology. What started with a few SRF cavities in the 1980s has now become a major field of activity. Today CERN is not only running a variety of superconducting RF installations and projects but is also preparing for a new collider, to follow the Large Hadron Collider (LHC), that will require pushing the limits of current technologies for better performance and lower cryogenic consumption.
Cryogenic thermal engineers are familiar with multilayer insulation (MLI), developed in the late 1950s as lightweight insulation for cryogenic propellants. MLI is used as high performance thermal insulation for launch vehicles, spacecraft, cryogenic tanks, dewars and spaceborne instruments. MLI operates in high vacuum, where its performance exceeds other insulations by a factor of ten. However, the heat leak through acreage MLI is still a major one for cryotanks, making it difficult to achieve the NASA goal of zero boiloff needed for long duration missions, and real world application of MLI also have some well-known challenges.
