Concrete Applications for Accelerator Science

Particle accelerators are a lot more than simply the engines of particle physics research, according to scientists working on the Accelerator Application Development and Demonstration (A2D2) project at Fermi National Accelerator Laboratory (CSA CSM). Electron beams generated by linear accelerators have all kinds of practical uses, the researchers say, such...

UK commits $88 Million to LBNF/DUNE Project

The United States and United Kingdom have entered into the first-ever umbrella science agreement between the two countries, a move that will see the UK contribute $88 million to the LBNF/DUNE project hosted at Fermi National Accelerator Laboratory (Fermilab, CSA CSM). The funding makes the UK the largest country investing...

IBM Reports Breakthrough in Quantum Computing

Simulating molecules on quantum computers just got easier according to new results obtained with IBM’s superconducting quantum hardware. In an article published in Nature, IBM researchers discuss the implementation of a new quantum algorithm capable of efficiently computing the lowest energy state of small molecules. By mapping the electronic structure...

Northrop Grumman to Acquire Orbital ATK for $9 Billion

Northrop Grumman Corporation has announced its plan to acquire Orbital ATK, Inc., a global leader in aerospace and defense technologies, for approximately $7.8 billion plus the assumption of $1.4 billion in net debt. The boards of both companies have approved the agreement and the transaction is expected to close in...

CEC/ICMC 2017 Conference Recap

Nestled against the coast of lake Monona in Madison WI, over 700 scientists and engineers from around the world bustled around the meeting rooms of Frank Lloyd Wright’s Monona Terrace from July 9-13, 2017, for the 21st joint Cryogenic Engineering and International Cryogenic Materials Conferences.

Flaw Uncovered in Modern Cryogenic Two-phase Flow Modeling

An investigation into popular thermal/fluid design codes begun as an exercise in curiosity by engineers at NASA Glenn Research Center and the University of Florida has uncovered an interesting flaw in modern cryogenic two-phase flow modeling.

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...

Wind Tunnels

Dr. Robert Kilgore The development of the cryogenic wind tunnel is one of many significant breakthroughs in both cryogenics and wind-tunnel technology made during the past millennium. Interest in the development of high-speed commercial and military aircraft resulted in a review of problems of flow simulation in transonic wind tunnels...

History of Cryogenics

From the Fall 1999 issue of Cold Facts magazine Millennium Breakthroughs A variety of CSA members give different perspectives on the past millennium: What were the most significant breakthroughs in cryogenics during the past millennium? Prof. R.G. Scurlock, Kryos Technology, scurlock@soton.ac.uk (“Breakthrough” = way through obstacles — Oxford English Dictionary)...

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...

Thermal shock on steel cylinder when dropped into liquid nitrogen

We are a research team at the University of South Florida, studying the “thermal shock” on a steel cylinder when it is dropped into liquid nitrogen. We want to make sure that the thermocouple does not get influenced by the surrounding LN2. Any advice?

Getter materials to absorb out gassed materials?

Here’s one for the scientists: We would like to sell vacuum insulated pipe for high temperature fluid applications. Are there any good getter materials that we can place in the vacuum space of our VJP to absorb outgassed materials at elevated temperatures?

Data on Carbon Fibres Reinforced Plastic at temperatures between 4 and 300K.

I am looking for data on Carbon Fibres Reinforced Plastic at temperatures between 4 and 300K. I would appreciate it if someone could give me some hints on where to find it.
