CLNG president responds to senator’s comments on LNG exports
In response to comments from U.S. Sen. Ron Wyden suggesting the United States needs a policy on energy exports and that a "timeout" should be declared on permits to export LNG to non-Free Trade Agreement countries, Center for Liquefied Natural Gas (CLNG) President Bill Cooper issued the following statement:
Linde introduces new N2 pressure booster
Gas-assist injection molders (GAIM) can improve efficiency and quality -- even on lightweight parts and difficult geometries -- with the help of a new liquid nitrogen (N2) pressure booster from Linde North America.
Argonne named a “Best Place” for postdocs to work
For postdoctoral scholars, or postdocs, Argonne National Laboratory is the 6th best place to work in the United States, according to The Scientist, a life sciences magazine.
At DOE, body blows to fusion, nuclear physics and particle physics
Overall, the 2013 budget numbers for the Department of Energy's (DOE's) Office of Science, the single largest funder of physical sciences research in the United States, look reasonably good. The office would see its budget climb by 2.4% to $4.992 billion. Three of the office's six major research programs, however,...
CERN experiment makes spectroscopic measurement of antihydrogen
In a paper published online on March 7 by the journal Nature, the ALPHA collaboration at CERN reports an important milestone on the way to measuring the properties of antimatter atoms.

Transfer Lines
Transfer lines may in some real sense be thought of as the cryogenic fluid analogy of current leads. While current leads carry electrical power to where it’s required in a cryogenic system, transfer lines do the same with cryogenic fluids. Transfer lines range in complexity from very simple U-tubes containing...
Zero Boiloff
Zero Boil Off cryostats are those that contain liquid cryogens but are designed to eliminate or vastly reduce the boil off of the liquid. These cryostats combine some of the advantages of Cryogen-Free systems (e.g. ease of use and long operational lifetime) with the advantages associated with a reservoir of liquid...
Cryomodule
Cryomodule is a term that is most commonly used to refer to cryostats that contain superconducting radio frequency (SRF) cavities. Such cavities are used to accelerate charged particle beams and are a major component of modern particle accelerators. Using the term cryomodule to refer to cryostats containing SRF cavities appears...
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...
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?
