This is the first part of a two-part article about cryogenic electronics, the operation of electronic devices, circuits and systems at temperatures considerably below the “standard” electronics lower limit of −55° C. Alternative names are cryoelectronics, cold electronics and low-temperature electronics. Presented by Dr. Randall Kirschman.

CSA regrets to report the loss of one of our own. Former Cold Facts editor Brian Dudley passed away peacefully in Tallahassee FL on January 9, 2021. He was 45.

Cornell scientists have identified a new contender when it comes to quantum materials for computing and low temperature electronics. Using nitride-based materials, the researchers created a material structure that simultaneously exhibits superconductivity—in which electrical resistance vanishes completely—and the quantum Hall effect, which produces resistance with extreme precision when a magnetic...

A team of scientists has detected the presence of a high-energy neutrino—a particularly elusive particle—in the wake of a star’s destruction as it is consumed by a black hole. This discovery, reported in the journal Nature Astronomy, sheds new light on the origins of Ultrahigh Energy Cosmic Rays—the highest energy...

Air Liquide Advanced Technologies (CSA CSM) has acquired 80% capital of the French company Cryoconcept, which specializes in dilution refrigeration technology reaching extremely low temperatures. This transaction enables Air Liquide to strengthen its expertise in the field of ultralow temperature—close to absolute zero—cryogenics, propose a broader offering and accelerate the...

In early December, DNV GL, a Norway-based, internationally accredited registrar and classification society, awarded a Dublin-based SuperNode Limited with a Statement of Feasibility for its “Subsea Superconducting Cable System” concept—technology that aims to connect renewable generation sources, increase grid interconnection in mature markets and decarbonize the electricity system.
