LHC physics data taking begins with new record collision energy
At 00:38 CEST on April 5, the LHC shift crew declared "stable beams" as two 4 TeV proton beams were brought into collision at the LHC’s four interaction points. This signals the start of physics data taking by the LHC experiments for 2012. The collision energy of 8 TeV is...
DOE scraps plans for neutrino experiment in mine
The US Department of Energy (DOE) is putting the brakes on the development of a gigantic experiment seen as the flagship project for the next decade at the country's sole particle physics laboratory.
Magnetic field researchers achieve hundred-tesla goal
Researchers at Los Alamos National Laboratory’s biggest magnet facility have met the grand challenge of producing magnetic fields in excess of 100 tesla while conducting six different experiments.
Leaders of faster-than-light experiment step down
Two leaders of the OPERA collaboration, which stunned the world in September when it announced data suggesting that neutrinos could travel faster than the speed of light, have stepped down.

Helium II
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...

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...

Metallic Salts Normally Used to Produce Ultra-Low Temperatures?
Regarding the method known as the Adiabatic Demagnetization of Paramagnetic Salts: What metallic salts are normally used to produce the ultra-low temperatures used for near-absolute-zero cryogenic research? Which salts are the most efficient? Which make the best cooling agents? And which are used most commonly by physicists? I am looking...
Specs and info on turbo expanders
I am a fourth year chemical engineering student doing a design project for the liquefaction of natural gas to DME and we are using a turbo expansion unit. I was wondering whether you would send me some specs and any additional information on turbo expanders that I could use as...
LN2 flow in cryotherapy device
I’m working on a cooler device that will be pretty similar to the devices commonly used in cryotherapy for cooling skin.
Sudden loss of vacuum in LHe storage dewar
I’m trying to find data on what happens when a 100 Liter LHe storage dewar experiences a catastrophic failure such as a sudden loss of vacuum. If anyone has any info on this subject, it would be very helpful.
