The US Department of Energy announced up to $39 million in available funding to support early stage R&D for innovative hydrogen and fuel cell technologies. Concept papers are due May 7, 2018, and full applications will be due June 12, 2018.

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...

Keeping the LHC Cold

The Large Hadron Collider is colder than interstellar space thanks to its cryogenic cooling system, with liquid helium pulsing through sophisticated plumbing that runs both inside and outside of the machine.

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.

EU Funds Research on “Cryosocieties”

The European Research Council has awarded a grant to researchers at Germany's Goethe University Frankfurt interested in understanding the social impacts of cryobiology. The research will focus on the freezing of umbilical cord blood as preparation for later regenerative therapies, the cryopreservation of egg cells for reproductive purposes and the...

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.

Liquid Hydrogen

Hydrogen becomes a liquid at 20K and 1 bar. Liquid hydrogen (LH2) is an important substance in industry, transportation and research. Industrial uses of hydrogen include applications in the electronics, glass, chemical and metal processing fields. In these applications, the hydrogen is generally used as a room temperature gas but...

Superconducting Radiofrequency Cavities

Superconducting radio frequency (SRF) cavities represent an important application of cryogenics and superconductivity. SRF cavities are a technology for accelerating charged particle beams via the transfer of radiofrequency (RF) energy to the beams via resonant structures. As such, they are frequently found in large particle accelerators used for scientific research....

Thermal Radiation Shields

Actively cooled thermal radiation shields are a common feature of cryostats whose lowest temperature is less than 77K. These shields, which typically operate at temperatures between that of LN2 and 40K, block thermal radiation from higher temperatures from reaching lower temperature cryogenic components or fluids. Since the heat radiated from...

Cryogenics in Space

Peter Kittel University of California-Berkeley pkittel@cal.berkeley.edu Space Cryogenics is the application of cryogenics to space missions. These applications fall into two broad areas, supporting space science missions and supporting the space transportation infrastructure. Science applications: The atmosphere is opaque to much of the electro-magnetic spectrum. In space, the absence of...

An Issue of Pressure and Flow Rate in a Supply Tank

Please help solve this problem: A supply tank requires a vaporizer to generate sufficient pressure to pump stored fluid up into a vehicle or tank. The available head is limited as the tank level falls and it is important to minimize the system pressure drop to maintain the desired flow...

Using MLI on VJ Line Joints or Cryo Storage Tanks

When installing Multi Layer Insulation (MLI) blankets on VJ line joints or cryo storage tanks should they be wrapped and tied down tight or loose? These are usually pre-cut to size. Also should they have an access hole at the point of where the molecular sieve is installed to help...
