MIT Spinoff Faces Challenges for its Planned Fusion Power Plant

Commonwealth Fusion Systems, an MIT spinoff based in Cambridge, aims to bring a fusion power plant online within 15 years—a timeline faster by decades than other fusion machines. The project will face a number of challenges, according to an analysis by IEEE, including fabricating and testing a new class of...

Link Discovered Between Superconductivity and Periodic Table

Scientists from Moscow Institute of Physics and Technology and Skoltech have discovered a general principle for calculating the superconductivity of hydrides based on the periodic table alone. The result, published in the Journal of Physical Chemistry Letters came as the group explored the superconductivity of actinium hydrides.

New Capabilities at NSLS-II Set to Advance Materials Science

Scientists at NSLS-II's Hard X-ray Nanoprobe (HXN) beamline have demonstrated the beamline's ability to observe materials down to 10 nanometers, about one ten-thousandth the diameter of a human hair. According to the team, this exceptionally high spatial resolution will enable scientists to "see" single molecules.

Dewar

A dewar is a type of cryostat named after Sir James Dewar, the researcher who first developed the concept of a vacuum insulated container with silvered walls to reflect thermal radiation. Dewar was the first to liquefy hydrogen, and he created the device to store his discovery. The thermos bottle...

Stirling and Gifford-McMahon Cryocoolers

Stirling and Gifford-McMahon (GM) cryocoolers are two of the most commonly used cryocoolers in cryogenics. Both devices have a significant industrial base and operate at a wide range of temperatures and capacities. The thermodynamic cycles for both of these cryocoolers are quite similar. The Stirling cycle consists of a compressor,...

Liquefied Natural Gas (LNG)

A significant commercial application of cryogenics is the liquefaction, transport and storage of natural gas. Liquefied Natural Gas (LNG) is generally 95 percent methane with a few percent ethane and much lower concentrations of propane and butane. LNG liquefies at 111.6 K. Unlike many applications of cryogenics, the motivation for...

Cryogenic Treatment of Materials

F.J. Diekman Controlled Thermal Processing, Inc. info@metal-wear.com Cryogenic Processing (also called cryogenic treatment, and incorrectly “cryogenic tempering”) is a process that uses cryogenic temperatures to modify materials to enhance their performance. Cryogenic Processing involves the slow reduction in temperature of the material to at least -300°F (-185°C) and holding the...

Containing ice accumulation while recovering helium

We are implementing a system to recover helium from our Janis ST-500 continuous flow LHe cryostat. The recovery system uses standard 1/4″ plastic tubing, which we connect directly to the cryostat’s exhaust port. The problem with this setup is that the gas is still quite cold as it leaves the...
