Work Begins to Boost LHC Luminosity

The Large Hadron Collider (LHC) at CERN officially entered a new stage with a groundbreaking ceremony to mark the start of the civil-engineering work for its High-Luminosity LHC (HL-LHC) upgrade. By 2026, this major project will considerably improve the performance of the LHC, increasing the number of collisions in the...

NOvA Reports Strong Evidence for Antineutrino Oscillation

For more than three years, scientists on the NOvA collaboration have observed neutrino particles as they oscillate from one type to another over a distance of 500 miles. Now, in a new result unveiled at the Neutrino 2018 conference in Heidelberg, Germany, the collaboration announced its first results using antineutrinos,...

NASA Developing Foam and Cork Insulation to Protect Deep Space Rocket

NASA is advancing state-of-the-art technology for thermal protection with more environmentally friendly materials and 3D printed molds for smaller parts. The agency says that extreme temperatures—ranging from -423°F to more than 200°F—call for novel thermal protection systems on the Space Launch System (SLS), its new heavy-lift rocket.

Spectroscopy Lab Finds New Property in Quantum Matter

A Johns Hopkins research team has proved that a particular quantum material can demonstrate electrical dipole fluctuations at conditions near -450°F, a theorized but never-before detected property involving irregular oscillations of tiny charged poles on the material.

Applied Superconductivity Center Names New Director

The reins of the Applied Superconductivity Center (ASC), hosted at the National High Magnetic Field Laboratory (CSA CSM), have been handed over to scientist and professor Lance Cooley, a CSA board director. Cooley takes over for his longtime mentor David Larbalestier, who will remain the chief scientist for materials at...

X-ray Tech Reveals Lost 19th Century Images

A team of scientists led by Western University in London, Ontario, Canada, has revealed how art curators can use light to recover images preserved on otherwise damaged daguerreotype silver plates.

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...

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...

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...

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...
