TRIUMF Celebrates New Five-Year Plan

The scientific community at TRIUMF (CSA CSM) recently gathered at its Advanced Rare Isotope Laboratory to celebrate the new Five-Year Plan for 2020-2025. It defines both the vision and mission for Canada's particle accelerator center, communicating the lab’s goals and strategies while laying out an action plan for the specified...

Lockheed Martin Reveals Human Lunar Lander Concept

Lockheed Martin revealed its concept for a crewed lunar lander during the International Astronautical Congress (IAC) in Bremen, Germany, showcasing how the reusable lander would align with NASA's lunar Gateway and future Mars missions.

National Geographic Introduces the Axion Dark Matter eXperiment

Take an informative written journey around ADMX with National Geographic writer Michael Greshko, who visited as "unassuming facility in northern Seattle" and was taken in by "a supercooled tangle of tubes and wires...poised to remake the world."

Celebrate Dark Matter Day 2018

Institutions around the world will celebrate Dark Matter Day throughout October, with events highlighting experiments that could bring us closer to solving the cosmic riddle of dark matter. The Interactions Collaboration, an international community of particle physics communication specialists, is the celebration's sponsor. Information on local events is available on...

Dr. Ursula Bassler Elected President of CERN Council

CERN's council has announced the election of Dr. Ursula Bassler as its 23rd president. She replaces professor Sijbrand de Jong on January 1, 2019, and will serve for a period of at least one year.

Stirling Technology Used at Italy’s First LNG Production Facility

DH Industries BV, a CSA CSM in the Netherlands, announced that Italy's first LNG production facility, using DH's Stirling technology, officially opened on September 27.

Dewar

A dewar is a type of cryostat named after Sir James Dewar, the researcher who first developed the concept of a vacuum insulated container with silvered walls to reflect thermal radiation. Dewar was the first to liquefy hydrogen, and he created the device to store his discovery. The thermos bottle...

Stirling and Gifford-McMahon Cryocoolers

Stirling and Gifford-McMahon (GM) cryocoolers are two of the most commonly used cryocoolers in cryogenics. Both devices have a significant industrial base and operate at a wide range of temperatures and capacities. The thermodynamic cycles for both of these cryocoolers are quite similar. The Stirling cycle consists of a compressor,...

Liquefied Natural Gas (LNG)

A significant commercial application of cryogenics is the liquefaction, transport and storage of natural gas. Liquefied Natural Gas (LNG) is generally 95 percent methane with a few percent ethane and much lower concentrations of propane and butane. LNG liquefies at 111.6 K. Unlike many applications of cryogenics, the motivation for...

Magnets

From “Superconductivity: Present and Future Applications” by the Coalition for the Commercial Application of Superconductors. Particle physics uses accelerators to recreate the conditions of the early universe in an attempt to piece together the complex puzzle of how we got to where we are today. These huge machines are used...

Energy Storage

From “Superconductivity: Present and Future Applications” by the Coalition for the Commercial Application of Superconductors. With power lines increasingly congested and prone to instability, strategic injection of brief bursts of real power can play a crucial role in maintaining grid reliability. Small-scale Superconducting Magnetic Energy Storage (SMES) systems, based on...

Astronomy

ASTRONOMY IN SPACE by Peter V. Mason, retired, Jet Propulsion Laboratory, and Visiting Associate, California Institute of Technology. Pmason@alumni.caltech.edu In thinking about the reasons to perform astronomy in space, we first consider the effect of the earth’s atmosphere. On a scale of decreasing energy, gamma rays, cosmic rays, X-rays and...

Cryocoolers

What is a Cryocooler? A mechanism that can extract heat from an object (cooler) and by doing so draw its temperature down below approximately 150 Kelvin (cryo). — (Courtesy Dr. Willy Gully) What is the difference between a Cryocooler and a Cryostat? A cryostat is any device designed to maintain...

Power usage: cryogenic systems vs. regular refrigerators

A recent project highlighted to me that closed cycle cryogenic cooling systems use far more electrical power to reduce temperatures by a few watts than regular refrigerators. I am sure it must be something to do with the extra difficulty of removing the heat from the liquid nitrogen or similar...

Redundancy strategies for mechanical -80C freezers

I was wondering what kind of redundancy strategies are people using for their mechanical -80C freezers? I am aware of the following. Please add if you are doing something different. 1) 1 Backup freezer for every 10 freezers – Empty and maintained at -80C at all times 2) Backup C02...

Safety guidelines for handling cryo vessels of nitrogen

I am looking for any safety guidelines for handling cryogenic vessels of nitrogen indoors and outdoors. I am especially interested in recommendations for area monitors to detect leaks, flow detection devices, etc.

Method to move components in a cryogenic environment

Does anyone know of a method with which to reliably move components in a cryogenic environment? We are interested in moving detectors in a cryogenically cooled (2K) vacuum chamber, which is contained within a larger cryostat/isolation vacuum with thermal shields. As the desired horizontal or vertical displacement is between 10...
