Fermilab NOvA experiment sees neutrinos change over 500 miles

Scientists on the NOvA experiment recently saw their first evidence of oscillating neutrinos, confirming that the extraordinary detector built for the project not only functions as planned but is also making great progress toward its goal of a major leap in our understanding of these ghostly particles.

LCLS measures ultrafast structural changes in ring-shaped gas molecules

For the first time, scientists have tracked ultrafast structural changes, captured in quadrillionths-of-a-second steps, as ring-shaped gas molecules burst open and unraveled. Ring-shaped molecules are abundant in biochemistry and also form the basis for many drug compounds. The pioneering study, conducted at SLAC's Linac Coherent Light Source (LCLS), points the...

First results from LHC Run 2 presented in Vienna

The world particle physics community convened in Vienna from July 22-29 for the 2015 European Physical Society Conference on High Energy Physics, where the latest results in the field were presented and discussed, including the first results from Run 2 of the Large Hadron Collider (LHC) at CERN. This was...

IceCube sees highest-energy neutrino ever found

On August 4, scientists working on the IceCube neutrino experiment at the South Pole reported the observation of a neutrino event that had an energy of more than 2000 trillion electron volts, making it the highest energy neutrino event ever found. The event offers scientists the best hope yet that...

UCLA scientists use large particle accelerator to visualize properties of nanoscale electronic materials

Using the large TRIUMF cyclotron in Vancouver, British Columbia, UCLA researchers have developed a new method to visualize topological insulators, a class of materials that could lead to improved performance in spintronics, at the nanoscale. The new method is the first use of beta-detected nuclear magnetic resonance to study the...

Nonmagnetic elements form unique magnet

Scientists at Rice University combined titanium and gold to make an itinerant antiferromagnetic metal, TiAu, from nonmagnetic constituent elements. While the uses for this particular magnet have yet to be determined, this discovery could enhance the scientific understanding of magnetism.

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...
