HEPTech: where academia meets industry

The high energy physics technology transfer network, or HEPTech, aims to bring together leading European high energy physics research institutions to provide academics and industry with a single point of access to the skills, capabilities, technologies and R&D opportunities of the high energy physics community in a highly collaborative open-science...

US scientists celebrate the restart of the LHC

After two years of upgrades and repairs to the world's most powerful particle accelerator, proton beams once again circulated around the Large Hadron Collider (LHC). With the collider back in action, the more than 1,700 US scientists who work on LHC experiments are prepared to join thousands of their international...

NASA Glenn celebrates Hubble’s 25th anniversary

NASA's Glenn Research Center in Cleveland OH is celebrating the launch of the Hubble Space Telescope 25 years ago this April with several activities for children and adults to learn more about Hubble's amazing contributions over the last quarter century.

The dawn of DUNE

The neutrino experiment formerly known as LBNE has transformed. Since January, its collaboration has gained about 50 new member institutions, elected two new spokespersons and chosen a new name: Deep Underground Neutrino Experiment, or DUNE. The proposed experiment will span 800 miles and will be the most powerful tool in...

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...

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...

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...
