With the delivery of two feedthrough samples for the 6 pin 30 KV rating, identified as a type D variant, Ceramtec North America Corporation (US) has begun to solve one of the big challenges at ITER.
Since shutting down in early 2013, the LHC and its detectors have undergone a multitude of upgrades and repairs. When the particle accelerator restarts, it will collide protons at an unprecedented energy: 13 trillion electron volts. The upgraded capabilities of the ATLAS, CMS, ALICE and LHCb detectors—plus the LHC’s extra...
Many industries are calling for electronics that can operate reliably in a harsh environment, including extreme temperatures above 200°C. A team of researchers from the University of California, Riverside and Rensselaer Polytechnic Institute discovered that molybdenum disulfide, a semiconductor material, may be a promising candidate to make thin-film transistors for...
In 2015, Fermilab will intensify its contribution to the Linac Coherent Light Source II (LCLS-II), an electron accelerator project at SLAC National Accelerator Laboratory, in the overlapping areas of superconducting radio-frequency accelerator technology and cryogenics.
Elevators are about to get a major upgrade: the ability to go sideways, thanks to magnetic levitation technology. German industrial behemoth ThyssenKrupp is promising that two-axis travel ("the holy grail of the elevator industry") will revolutionize intra-building travel, and that they will have it operational in 2016.
A new study by a team of physicists adds to the growing body of evidence supporting a theory that strange electronic behaviors, including high temperature superconductivity and heavy fermion physics, arise from quantum fluctuations of strongly correlated electrons. The study describes results from a series of experiments that tested for...
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 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 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...

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...
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...
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...
I was looking for suppliers of regenerator materials. Can you please provide a list of vendors for: • Lead spheres • Bronze screen discs • Rare earth materials and spheres Thank you in advance for any help you can provide.
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...
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...
