KEK Director General assesses earthquake damage, tells repair plans

Atsuto Suzuki, Director General at KEK, the Japanese high energy accelerator research organization, reported on damage caused by the recent earthquake and recovery prospects in his “DG’s Corner” column: First of all, I would like to express my deepest appreciation for the messages of concern, sympathy and encouragement that we...

Superconductivity pioneer Paul Chu featured in exhibit

Superconductivity Pioneer Paul Chu was featured in an unusual exhibit in Texas. A white lab coat and a pair of worn sneakers are almost standard-issue items for a research facility, but they don't seem to rise to the rank of museum exhibit. Yet, that’s exactly where you can find one...

Paul Chu expected more progress by now

Superconductivity pioneer Dr. Paul Chu expected faster progress since his discoveries, he told Cold Facts Editor Theresa Boehl in a recent brief interview. Cold Facts: Did you have any idea of the potential impact of superconductivity when you were doing your groundbreaking research years ago? Chu: Yes, I think I...

Mathias Kläui Wins Kurti Science Prize

Oxford Instruments NanoScience announced that Professor Mathias Kläui from the SwissFEL, Paul Scherrer Institut and the Laboratory of Nanomagnetism and Spin Dynamics, École Polytechnique Fédérale de Lausanne, is the 2011 recipient of the Nicholas Kurti European Science Prize.

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...

Transfer Lines

Transfer lines may in some real sense be thought of as the cryogenic fluid analogy of current leads. While current leads carry electrical power to where it’s required in a cryogenic system, transfer lines do the same with cryogenic fluids. Transfer lines range in complexity from very simple U-tubes containing...

Zero Boiloff

Zero Boil Off cryostats are those that contain liquid cryogens but are designed to eliminate or vastly reduce the boil off of the liquid. These cryostats combine some of the advantages of Cryogen-Free systems (e.g. ease of use and long operational lifetime) with the advantages associated with a reservoir of liquid...

Cryomodule

Cryomodule is a term that is most commonly used to refer to cryostats that contain superconducting radio frequency (SRF) cavities. Such cavities are used to accelerate charged particle beams and are a major component of modern particle accelerators. Using the term cryomodule to refer to cryostats containing SRF cavities appears...

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...

Looking for manufacturers of cryogenic dewars with infrared detectors (long wave)

We are looking for manufacturers of cryogenic dewars with infrared detectors (long wave). We need these dewars for repairing infrared systems (thermographic systems) and we cannot find such glass dewars. Do you know any manufacturers’ addresses?

Manufacturers of cryogenic regenerator lead spheres?

Would you please suggest a few manufacturers that produce cryogenic regenerator lead spheres? The size we need is 0.15mm-0.2mm. I don’t have a lot of ideas for where to go to purchase them.

Assistance with resolving a sealing problem?

We are fabricating piping components for refrigeration service. These components must be leak checked at 15 bar (218 psig). We are using a gas test media that is 25% helium and experiencing difficulty on maintaining a seal on the flanged connections. Do you know anyone or any references that could...

Cryogenic data on leather and nomex

Could anyone please help me out with the following cryogenics data: Leather — mechanical properties at 77 K or lower Nomex — thermal conductivity @ 4 to 50 K I lost the data I had some time ago and although this should be easily accessible, I can’t find any reference...
