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...

You are encouraged to read Cryo Central’s History...

Bose-Einstein Condensate

A Bose-Einstein condensate, first proposed in 1925 by Albert Einstein based on work done by Satyendra Nath Bose (the same Bose from whom the term boson is derived), is a super-cold state of matter in which almost all of the individual atoms have “condensed” down to the lowest possible quantum...

Cold Technology for Pest Control

While it does not reach temperatures cold enough to be called cryogenic, carbon dioxide snow is at the heart of a new way of dealing with unwanted pests. It utilizes a quick freezing process that takes advantage of the properties of carbon dioxide snow and has a number of benefits...

Cryogenic Finishing

The following 3 articles discuss the uses and procedures of various type of cryogenic finishing. 1) By Robin A. Rhodes, Cryogenic Institute of New England, Inc. rrhodes@nitrofreeze.com Cryogenic Deflashing is employed to remove undesired residual mold flash that remains on molded parts after they are removed or ejected from the...
