Erica Messer and “Criminal Minds” get cryogenics/cryonics right

CSA sent kudos to Erica Messer, show runner for the CBS series “Criminal Minds,” for getting the important distinction between cryogenics and cryonics right, and putting the explanation into the mouth of the show’s smartest character.

Brookhaven dedicates “brightest beacon at the frontiers of discovery”

The National Synchrotron Light Source II (NSLS-II) at Brookhaven Laboratory was dedicated February 6. NSLS-II, which produces extremely bright beams of X-ray, ultraviolet and infrared light, will examine a wide range of materials, including superconductors and catalysts, geological samples, and biological proteins, to accelerate advances in energy, environmental science and...

First prototypes of high-voltage feedthrough

With the delivery of two feedthrough samples for the 6 pin 30 KV rating, identified as a type D variant, Ceramtec North America Corporation (US) has begun to solve one of the big challenges at ITER.

What’s new for LHC Run II

Since shutting down in early 2013, the LHC and its detectors have undergone a multitude of upgrades and repairs. When the particle accelerator restarts, it will collide protons at an unprecedented energy: 13 trillion electron volts. The upgraded capabilities of the ATLAS, CMS, ALICE and LHCb detectors—plus the LHC’s extra...

Potential of molybdenum disulfide for extreme-temperature electronics

Many industries are calling for electronics that can operate reliably in a harsh environment, including extreme temperatures above 200°C. A team of researchers from the University of California, Riverside and Rensselaer Polytechnic Institute discovered that molybdenum disulfide, a semiconductor material, may be a promising candidate to make thin-film transistors for...

Fermilab contributes to SLAC LCLS-II with cutting-edge technology and expertise

In 2015, Fermilab will intensify its contribution to the Linac Coherent Light Source II (LCLS-II), an electron accelerator project at SLAC National Accelerator Laboratory, in the overlapping areas of superconducting radio-frequency accelerator technology and cryogenics.

Helium II

Helium II (He II) refers to the second liquid phase of the most abundant helium isotope (4He). Helium II is also referred to as superfluid helium. Helium II occurs once the temperature of the liquid helium drops below 2.17K. The phase transition between the first liquid phase of Helium (referred...

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?
