In a series of lab experiments on exotic materials, scientists from the University of California and Stanford University have discovered "firm evidence" of particles that are their own antiparticles. Physicists have been looking for such Majorna fermions since physicist Ettore Majorana predicted them in 1937. The result is currently more...

Researchers from the LHCb experiment at CERN reported the observation of a new particle from the baryon family. It contains two charm quarks and one up quark. The mass of the newly identified particle is about 3621 MeV, almost four times heavier than the most familiar baryon, the proton, a...

NIST researchers have developed an automated probe system to evaluate computer components submitted by both private sector and federal labs to the Cryogenic Computing Complexity (C3) program. C3 aims to enable a new generation of low-power superconducting supercomputers that operate at liquid helium temperatures and use ultra-fast switching of microscopic...

Many projects in applied superconductivity hold great promise for the energy sector, but have failed to catch on due to cost, competition from established systems, perceived risk and other factors. Among them is Superconducting Magnetic Energy Storage (SMES), a system that stores energy in the form of a magnetic field....

Integrated Refrigeration and Storage (IRAS) is a technology to help maximize efficiency of spaceport cryogenic processes by integrating modern cryogenic refrigeration units with liquid storage vessels. Brayton cycle helium refrigerators are available in a range of capacities and temperatures, with demonstrated high efficiency and low maintenance. In an IRAS system,...

Affordable and reliable cryogenic fluid storage for propellant or life support systems is integral to all phases of NASA’s projected space and planetary expeditions. One challenge facing engineers is self-pressurization. It can be caused by the cryogen vaporization that results from heat leaks into a tank from its surroundings and...
