Beam Delivered to Muon g-2, First Results Expected Later this Year

Accelerators at the Fermi National Accelerator Laboratory (CSA CSM) have delivered beam to the Muon g-2 experiment for the first time, kicking off a three-year effort to measure what happens to those particles when placed in a precise magnetic field. The answer could rewrite scientists’ picture of the universe and...

NY Allocates $15 Million for Brookhaven Cryo-Electron Microscope

The Brookhaven National Laboratory has announced a $15 million allocation from New York State to fund a cryo-electron microscope at the Long Island Facility for Electron Microscopy, a new facility on its campus. The microscope will operate at 77 K and will provide researchers with a new look at molecular...

Sandwiched Graphene Adopts Andreev States

MIT physicists have found that a flake of graphene, when sandwiched between two superconducting materials, can inherit some of those materials’ superconducting qualities. The electronic state of the graphene changes dramatically here, even at its center, as the particles pair up in Andreev states—a fundamental electronic configuration that allows a...

Auguste and Taylor-Wharton Ink New Distribution Deal

Auguste Cryogenics has signed a long-term liquid cylinder distribution agreement with Taylor-Wharton, becoming the exclusive distributor in Europe, Russia and Israel for Taylor-Wharton’s extensive line of gas and liquid withdrawal cylinders.

Researchers Develop Circuit Refrigerator for Quantum Computers

Cooling has proven to be a major concern for engineers developing quantum computers, but now a research team at Finland's Aalto University says it has invented a quantum circuit refrigerator that could reduce errors in quantum computing. Quantum computers differ from the computers that we use in that, instead of...

Ball Aerospace Developing Cryostat for GUSTO

NASA has chosen Ball Aerospace to design and build a cryostat for its Galactic/Extragalactic Ultralong Duration Balloon (ULDB) Spectroscopic Terahertz Observatory mission, or GUSTO. The mission, led by the University of Arizona, will measure emissions from the interstellar medium, helping scientists to determine the life cycle of interstellar gas in...

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...
