DESY awards contract for 120 RF cavities

RI Research Instruments GmbH, a majority-owned subsidiary of Bruker Energy & Supercon Technologies, Inc. (BEST), announced the award of a contract for five radio frequency (rf) cavities for the Facility for Antiproton and Ion Research (FAIR) project, valued at approximately $5.8 million.

Use of cryoablation for treatment of breast cancer shows promising results

IceCure Medical reports that Dr. Eisuke Fukuma has treated 58 breast cancer patients with cryoablation over the last six years under a research protocol at Kameda Medical Center in Japan. As of now, they say, none of the patients have had a tumor reoccur or distant metastases. By choosing this...

Japan minister seeks quick OK for US LNG imports

Japanese trade minister Toshimitsu Motegi called for early approval for exports of liquefied natural gas to Japan in a meeting with Acting Energy Secretary Daniel Poneman, saying securing a relatively cheap energy source is crucial for Japan, Kyodo news reported.

Oxford Instruments announces winner of 2013 Nicholas Kurti European Science Prize

Dr. Lapo Bogani from the Universität Stuttgart has been awarded the 2013 Nicholas Kurti European Science Prize. This prestigious award is sponsored by Oxford Instruments, a leading provider of high technology tools and systems for industry and research.

Physicists build world’s first ‘magnetic hose’ for transmitting magnetic fields

One of the more important properties of electromagnetic waves is that they can be transmitted over almost unlimited distance. However, the same cannot be said of magnetic fields. "The impact of magnetism in science is limited by an apparently insurmountable restriction: magnetic fields rapidly decay with the distance from the...

GE researcher receives 200th US patent

GE Global Research, the technology development arm of the General Electric Co., is honored to announce that Dr. E. Trifon Laskaris, Chief Engineer and pioneer in imaging technologies, has been awarded his 200th U.S. patent—a milestone previously reached by only one other GE research lab employee, Thomas Edison.

Joule-Thomson Effect

The Joule-Thomson (JT) effect is a thermodynamic process that occurs when a fluid expands from high pressure to low pressure at constant enthalpy (an isenthalpic process). Such a process can be approximated in the real world by expanding a fluid from high pressure to low pressure across a valve. Under...

Current Leads

One of the challenges of using superconducting magnets is the connection of the magnet to a room temperature power supply. This is accomplished via current leads. The trick is that current leads should ideally have a low heat leak, since they connect room temperature to cryogenic temperature, while at the...

Multilayer Insulation

Multilayer insulation (also referred to as superinsulation) is a key component in the reduction of heat leak to cryogenic systems due to thermal radiation. MLI consists of a series of uncooled reflective surfaces placed in the vacuum space between two surfaces, one warmer than the other. Generally speaking, for ideal...

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...

Information about a process called “cryogenically stretch-formed ss”

I am remembering in the 1970’s when astronauts were walking on the moon and carried oxygen in 300 ss bottles inside LN2 tanks which were filled and pressurized.

Small cryo-gun for our health service clinic

Additional sealing materials besides PTFE or glass filled PTFE

I am an engineer looking to improve our solenoid valve sealing on cryogenic medias. I was wondering if you knew of materials other then PTFE or glass filled PTFE that could be used for sealing.

What is the temperature range of cryogenics?

Could you please tell me what is the temperature range of cryogenics? In other words, is -100°F considered cryogenic, or does it start lower? Could I expect to see some extended life in D2 stamping dies? What would the recipe be to achieve the desired results using cryogenics?
