NASA to send up teachers on SOFIA

NASA has selected six teachers to work with scientists aboard the Stratospheric Observatory for Infrared Astronomy (SOFIA) during research flights in May and June. This is the first team of educators selected to participate in SOFIA’s Airborne Astronomy Ambassadors program.

LBNE Takes a “Hive’s Worth” of Experts

In the May symmetry, in an article titled, “LBNE: the inside buzz on a new science project,” Amelia Williamson Smith reports that planning and designing the $900 million Long Baseline Neutrino Experiment takes more than a village. It takes a hive’s worth of scientists, engineers, technicians, accountants, and other specialists...

More than 15,000 attend Goddard Open House

NASA’s Goddard Space Flight Center in Greenbelt MD hosted more than 15,000 visitors under gray but rain-free skies on May 14. The Explore@NASA Goddard event was the center’s first open house since 2008, according to Robert Garner of the Center.

Berkeley Lab Researcher Wins DOE Early Career Award

Among the 65 Early Career Research Program award recipients announced last week by DOE’s Office of Science is Paolo Ferracin of the Superconducting Magnet Group in the Accelerator and Fusion Research Division at Lawrence Berkeley Laboratory.

Specifications or drawings for a 3/4" X 18" Brookhaven Bayonet

Does anyone have the specifications or know where we can find drawings for a 3/4″ X 18″ Brookhaven Bayonet?

LHC sets world record beam intensity

The CERN Large Hadron Collider on April 22 set a new world record for beam intensity at a hadron collider when it collided beams with a luminosity of 4.67 x 1032cm-2s-1.

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...

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...
