TRIUMF and KEK strengthen partnership to advance physics research

At a signing ceremony hosted on December 4 at the Canadian Embassy in Japan, the heads of Canada’s TRIUMF and Japan’s KEK signed a new partnership agreement to enhance research collaborations between the two centers and promote joint projects in the areas of subatomic physics, accelerator science and materials science.

Researchers developing shoebox-sized particle accelerator

The Gordon and Betty Moore Foundation in November awarded $13.5 million to Stanford University for an international effort, including key contributions from the Department of Energy’s SLAC National Accelerator Laboratory, to build a working particle accelerator the size of a shoebox. The technique, based on a technology known as “accelerator...

Innovation boosts study of fragile biological samples at SLAC’s LCLS

Researchers at the Department of Energy's SLAC National Accelerator Laboratory have found a simple new way to study very delicate biological samples—like proteins at work in photosynthesis and components of protein-making machines called ribosomes—at the atomic scale using SLAC's Linac Coherent Light Source (LCLS) X-ray laser.

SCOAP3 outlines its impact on open access publishing

The SCOAP3 (Sponsoring Consortium for Open Access Publishing in Particle Physics) executive committee on November 18 held an online forum to discuss the partnership’s impact since its founding in nearly two years ago. SCOAP3 members include libraries, publishers, funding agencies and research centers in more than 40 countries with CERN...

Worthington acquires Taylor Wharton’s CryoScience business

Worthington Industries, Inc., announced its cryogenics business in the pressure cylinders segment is purchasing the assets of the global CryoScience business of Taylor Wharton Cryogenics, including a manufacturing facility in Theodore AL. Worthington will also acquire certain other intellectual property and manufacturing assets of Taylor Wharton focused on the cryogenic...

NASA’s Webb Pathfinder telescope successfully completes second super-cold optical test

Recently, the James Webb Space Telescope's "pathfinder telescope," or "Pathfinder," completed its second super-cold optical test. This marked the first check of specialized optical test equipment designed to illuminate the telescope's optics through to the instrument focal plains, as well as the procedures used to operate this test equipment.

Stability

Stability refers to the ability of a device employing superconductors to remain in its superconducting state after part of the superconductor transitions back to its normal conducting state due to a disturbance. While the concept can apply to many superconducting devices—transmission lines, generators, motors, etc.—it is most commonly considered in...

Cable-in-Conduit Conductors

Cable-in-Conduit Conductors (CICC) are a common form of superconducting cable used in large-scale applications. There are several varieties of CICCs, but they all consist of many small, stabilized superconducting wires contained within a conduit through which a coolant (typically supercritical He II) flows. Figure 1 shows the cross section of...

Bayonet Coupling

A bayonet coupling is a demountable joint that allows for quick and easy connection and disconnection of cryogenic components, including transfer lines, cryostats, liquefiers and refrigerators. Bayonets provide a number of advantages, chief among them the ability to connect and disconnect the bayonets while components they connect are still at...

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...
