A team of researchers from MIT, CERN and the KFKI Research Institute for Particle and Nuclear Physics in Budapest, Hungary has completed work on the first scientific paper analyzing the results of collisions at the LHC.
M&I Materials visited by the Prince of Wales
In early February, M&I Materials was visited by the Prince of Wales at their Manchester UK facility.
TcSUH receives $3.5 million grant
The University of Houston's Texas Center for Superconductivity (TcSUH) has received a $3.5 million grant from the Texas Emerging Technology fund (TETF) to help expand the research capabilities of the center's Applied Research Hub.
Oxford Instruments delivers its 50th Cryofree® dilution refrigerator
Oxford Instruments announced in late January that the company has delivered its 50th Cryofree® dilution refrigerator, which allows for cooling of samples to temperatures below 10mK without the need for liquid helium.
Brookhaven, AES open facility to produce SRF cavities
Brookhaven National Laboratory and Advanced Energy Systems have opened a hi-tech facility at the AES site that will produce superconducting radiofrequency (SRF) cavities for particle accelerators.

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...
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...
Eliminate negative effects of grinder burn on gear teeth?
Can you tell me if it is possible to eliminate the negative affects of grinder burn on gear teeth with the use of cryogenics?
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
I am Assistant Director for Environmental Health & Safety at a university 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.
