Fermilab Accelerator Division demonstrates Booster Neutrino Beamline operations

After five months of repairing and retooling the Booster Neutrino Beamline (BNB), members of the Accelerator Division at Fermi National Accelerator Laboratory successfully delivered beam to the BNB on June 22. The previous horn, BNB-2, was found to be inoperable in January when it was determined its cooling was no...

Used MRI magnets get a second chance at life in high energy physics experiments

Researchers at the US Department of Energy's Argonne National Laboratory recently acquired two decommissioned magnets from magnetic resonance imaging (MRI) scanners from hospitals in Minnesota and California that will find a new home as proving grounds for instruments used in high energy and nuclear physics experiments. The two new magnets...

Physicist Peter Winter wins DOE Early Career Award

High energy physicist Peter Winter of the US Department of Energy's (DOE) Argonne National Laboratory has received a DOE Early Career Award, a prestigious five-year research grant totaling $2.5 million. The grant will help to fund Winter's contributions to the muon g-2 experiment currently being assembled at Fermi National Accelerator...

NASA issues request for information on Stirling power systems

NASA’s Science Mission Directorate is seeking information on Stirling power systems and technologies that could be developed into a space-based power system that would provide between 100-500 Watts of electricity for future deep space missions. In partnership with the Department of Energy, a Request for Information (RFI) posted on June...

X-ray ptychography, fluorescence microscopy combo sheds new light on trace elements

Using the Advanced Photon Source, a US Department of Energy Office of Science User Facility at Argonne National Laboratory (CSA Corporate Sustaining Member), a team of researchers demonstrated unparalleled sensitivity for measuring the distribution of trace elements in thicker specimens at cryogenic temperatures, in this case at about -260°F. They...

Toward a resolution of the proton form factor problem

In the paper "Towards a Resolution of the Proton Form Factor Problem: New Electron and Positron Scattering Data" published in Physical Review Letters, D. Adikaram et al. report findings that may resolve a puzzle that has confounded physicists for the last decade: the baffling discrepancy between measurements of two different...

Helium II

Helium II (He II) refers to the second liquid phase of the most abundant helium isotope (4He). Helium II is also referred to as superfluid helium. Helium II occurs once the temperature of the liquid helium drops below 2.17K. The phase transition between the first liquid phase of Helium (referred...

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...

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...
