ICARUS neutrino experiment to move to Fermilab

A group of scientists led by Nobel laureate Carlo Rubbia will transport the world’s largest liquid-argon neutrino detector across the Atlantic Ocean from CERN to its new home at the US Department of Energy’s Fermi National Accelerator Laboratory. When it arrives at Fermilab, the detector will become part of an...

Mu2e breaks ground on experiment seeking new physics

Members of the Mu2e collaboration recently dug their shovels into the ground of Fermilab's Muon Campus for the experiment that will search for the direct conversion of a muon into an electron in the hunt for new physics.

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...

Elsevier’s new open access journal Heliyon now accepting submissions

Elsevier has announced the call for submissions for its new open access journal Heliyon. The journal will be a publishing platform for sound research developed in collaboration with the research community so as to offer researchers a new publishing option tailored to their needs.

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 awards contract for test facilities operations, maintenance and engineering

NASA has selected HX5 Sierra, LLC, of Fort Walton Beach FL to provide operations, engineering and maintenance support services test facilities and laboratories for the agency's Glenn Research Center in Cleveland and Plum Brook Station in Sandusky OH.

Regenerators

Regenerators or regenerative heat exchangers are a key component of cryocoolers such as pulse tube cryocoolers (Cold Facts, August 2014). Regenerator performance greatly affects the coefficient of performance of cryocoolers. Improvements in regenerator design and, in particular, regenerator materials have been an important factor in the improvement of the performance...

Pulse Tube Cryocoolers

The development of pulse tube cryocoolers has been a significant topic of research and development over the past 20 or so years. Pulse tube cryocoolers have a number of advantages over other types of cryocoolers and are now available commercially. In order to understand pulse tube cryocoolers, it’s best to...

Thermal Expansion

Thermal expansion refers to the change in size (length or volume) that a material undergoes as its temperature changes. In cryogenic systems this effect can be quite large and must be allowed for in the design. In isotropic materials, which include most engineering materials, the thermal expansion is the same...

Cryobiology

Andreas Sputtek Past President Society for Cryobiology sputtek@uke.uni-hamburg.de or http://www.sputtek.de/. The word cryobiology (from the Greek words “cryo” = cold, “bios” = life, and “logos” = science) literally signifies the science of life at low temperatures. In practice, this field comprises the study of any biological material or system (e.g.,...

Cryogenic Insulation

James E. Fesmire Cryogenics Test Laboratory NASA Kennedy Space Center james.e.fesmire@nasa.gov Introduction In today’s world, the use of cryogenics and low-temperature refrigeration is taking a more and more significant role. From the food industry, transportation, energy, and medical applications to the Space Shuttle, cryogenic liquids must be stored, handled, and...

Cryogenic Treatment of Materials

F.J. Diekman Controlled Thermal Processing, Inc. info@metal-wear.com Cryogenic Processing (also called cryogenic treatment, and incorrectly “cryogenic tempering”) is a process that uses cryogenic temperatures to modify materials to enhance their performance. Cryogenic Processing involves the slow reduction in temperature of the material to at least -300°F (-185°C) and holding 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...
