On October 8 François Englert of Belgium and Peter Higgs of Britain were awarded the 2013 Nobel Prize in physics for their theoretical discoveries on how subatomic particles acquire mass.
The Compact Linear Collider (CLIC) is a study for a future accelerator that will reach unprecedented energies for electrons and their antimatter twins, positrons.
Fiber optics has made communication faster than ever, but the next step involves a quantum leap—literally. In order to improve the security of the transfer of information, scientists are working on how to translate electrical quantum states to optical quantum states in a way that would enable ultrafast, quantum-encrypted communications.
In connection with its recent acquisition of substantially all the assets of the Salof Companies, GE Oil & Gas announced that it has completed its acquisition of a 50 percent ownership interest in Beijing enCryo Engineering Co., Ltd., a Beijing-based joint venture with Beijing Maison Engineering Co., Ltd. that specializes...
After seeing possible hints of surprisingly light dark matter earlier this year, scientists on the Cryogenic Dark Matter Search have found a way to improve their search for such particles.
Helium II (He II) refers to the second liquid phase of the most abundant helium isotope (4He). Helium II is also referred to as superfluid helium. Helium II occurs once the temperature of the liquid helium drops below 2.17K. The phase transition between the first liquid phase of Helium (referred...

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 have to maintain a certain mass (some tons) at 100 K by circulating in it GHe (through apposite channels). How can I calculate the flow rate needed? I suppose that the delta T (T inlet and T outlet) and the heat load on the mass are necessary. Knowing the...
