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.

Adiabatic Demagnetization Refrigeration

Reaching temperatures below 1K requires different techniques than the various helium gas cycles found in large scale refrigeration plants and small cryocoolers. One of these techniques is Adiabatic Demagnetization Refrigeration (ADR). This technique takes advantage of the fact that the entropy of paramagnetic materials in a magnetic field is lower than...

Cryogen-Free

A cryogen is any fluid that operates at cryogenic temperatures (below roughly 150K – 120K). Using this definition, helium gas at 40K is a cryogen. Another more restrictive definition is to use cryogen to refer specifically to liquids at cryogenic temperatures. This is generally how it is used in the...

Cryostats and Cryocoolers

A cryostat is any device designed to maintain things (including fluids) at cryogenic temperatures. In general usage, cryostats tend to be passive devices rather than providing active cooling. In this usage, cryostats keep things cold by thermally isolating them from room temperature. This generally is accomplished by a combination of...

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...

Cryogenics in Space

Peter Kittel University of California-Berkeley pkittel@cal.berkeley.edu Space Cryogenics is the application of cryogenics to space missions. These applications fall into two broad areas, supporting space science missions and supporting the space transportation infrastructure. Science applications: The atmosphere is opaque to much of the electro-magnetic spectrum. In space, the absence of...

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...

Separated layers of ice over a pipe

I want to know that why there are different layers of ice over a pipe carrying a cryogenic fluid, each layer separated with clear marks / lines? What do these layers signify?
