First results from LHC Run 2 presented in Vienna

The world particle physics community convened in Vienna from July 22-29 for the 2015 European Physical Society Conference on High Energy Physics, where the latest results in the field were presented and discussed, including the first results from Run 2 of the Large Hadron Collider (LHC) at CERN. This was...

IceCube sees highest-energy neutrino ever found

On August 4, scientists working on the IceCube neutrino experiment at the South Pole reported the observation of a neutrino event that had an energy of more than 2000 trillion electron volts, making it the highest energy neutrino event ever found. The event offers scientists the best hope yet that...

Nonmagnetic elements form unique magnet

Scientists at Rice University combined titanium and gold to make an itinerant antiferromagnetic metal, TiAu, from nonmagnetic constituent elements. While the uses for this particular magnet have yet to be determined, this discovery could enhance the scientific understanding of magnetism.

Fermilab’s flagship accelerator sets world record

On July 8, scientists announced that the US Department of Energy's Fermi National Accelerator Laboratory (Fermilab, CSA CSM) set a world record for the most powerful high-energy particle beam for neutrino experiments: a sustained 521-kilowatt beam generated by the Main Injector particle accelerator. More than 1,000 physicists from around the...

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...

Food Processing

Cryogenics and Food The industrial gas industry provides a host of products and services related to food. The various gases have useful and sometimes fascinating applications in food industry. “The food industry is not a homogenous industry. The needs of customers processing hamburger vs. poultry vs. strawberries vs. seafood, for...

Primary Standards

Elie K. Track Hypres, Inc. elie@hypres.com http://www.hypres.com/ Primary standards involve the exact definition and realization of units of measurement for various quantities, time, length, mass, voltage, resistance, current, etc. International agreements based on the latest scientific knowledge define those units, and their realizations vary depending on the unit itself. For...

Shrink Fitting

Robin A. Rhodes Cryogenic Institute of New England, Inc. rrhodes@nitrofreeze.com Shrink fitting, (or “compression fitting” as it is sometimes called), is a method used to insert a pin or bushing into a housing or other assembly requiring an extremely tight tolerance fit. It can be used as an alternative to...

Telecommunications

From the Winter 2004 issue of Cold Facts magazine The recent M-Calc IV — 4th Industry Assessment workshop discussing military and commercial applications for low-cost cryocoolers, held in November in San Diego, highlighted progress being made in cryogenics as applied in telecommunications. The reliability and long lifetime of projects now...

An Issue of Pressure and Flow Rate in a Supply Tank

Please help solve this problem: A supply tank requires a vaporizer to generate sufficient pressure to pump stored fluid up into a vehicle or tank. The available head is limited as the tank level falls and it is important to minimize the system pressure drop to maintain the desired flow...

Using MLI on VJ Line Joints or Cryo Storage Tanks

When installing Multi Layer Insulation (MLI) blankets on VJ line joints or cryo storage tanks should they be wrapped and tied down tight or loose? These are usually pre-cut to size. Also should they have an access hole at the point of where the molecular sieve is installed to help...
