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 to 1638 Pa (16 mbar). … Continue reading Cold Compressors

UH wind turbine superconductivity research project wins additional funding
A University of Houston engineering researcher and his team have received additional funding from the US Department of Energy (DOE) for a wind energy project that involves using superconducting wire to generate and transport electricity.
Fermilab scientists selected as APS fellows
Five Fermilab scientists have been named fellows of the American Physical Society, a distinction awarded each year to no more than one-half of 1 percent of current APS members by their peers.
Nexans and AMSC introduce fault current limiter for North American utilities
AMSC, a global solutions provider serving wind and grid leaders, and Nexans, an expert in the cable industry (both CSA Corporate Sustaining Members), recently introduced to the North American market a medium voltage superconductor fault current limiter (SFCL) solution that is designed to meet many of the challenges caused by today's highly interconnected networks and diversified generation sources.
“Crowning” the ITER cryostat from below solves columnar design problem
Columns are as old as civilization: for thousands of years, they have provided architects and engineers with a simple and sturdy solution to support heavy loads while leaving room to move around on the ground below. This traditional and reliable solution was to be implemented in ITER.
DOE study: LNG exports to benefit American economy
The US Department of Energy (DOE) has released its study on the economic impacts of liquefied natural gas (LNG) exports. DOE’s analysis finds that the US economy will experience “net economic benefits” from allowing increased LNG exports. It found that the natural gas boom has helped create jobs and spur economic growth.
Science and engineering students petition Congress: Stop sequestration
Science and engineering students have hand-delivered a petition to the local offices of all US senators and House leaders, requesting that sequestration be halted because it would harm their future as innovators and hurt economic growth in the United States. The students represent numerous scientific societies across the United States, including the American Physical Society.
Lake Shore issues new model CRX-VF probe station specifications
Lake Shore Cryotronics, a CSA Corporate Sustaining Member, has introduced updated specifications for its Model CRX-VF cryogenic probe station, which features increased maximum magnetic field, improved magnetic field at elevated sample temperatures and improved vacuum performance.
Scientists discover new phi-Josephson junction for use in cryoelectronics
Scientists from the University of Tübingen, Germany, working with colleagues from Tel Aviv University and the University of Kiel, Germany, have proposed [1] and experimentally demonstrated [2] a new type of superconducting element – named the phi-Josephson (?-Josephson) junction. Implemented in cryogenic devices, this element will make superconducting electronic circuits work practically “by themselves” and improve functionality.
