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.

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...

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...

Containing ice accumulation while recovering helium

We are implementing a system to recover helium from our Janis ST-500 continuous flow LHe cryostat. The recovery system uses standard 1/4″ plastic tubing, which we connect directly to the cryostat’s exhaust port. The problem with this setup is that the gas is still quite cold as it leaves the...

Looking for some advice regarding cryogenic modeling in ANSYS FEA software

I am looking for some advice regarding cryogenic modeling in ANSYS FEA software. I have been trying to use the Transient Thermal module, in workbench 14.5, to model the cooling of a device in a dilution fridge. I have approximate values for the cooling power of each plate in the...
