2017 Nobel in Physics Celebrates Discovery of Gravitational Waves

The Royal Swedish Academy of Sciences awarded its 2017 Nobel Prize in Physics to Drs. Rainer Weiss, Barry Barish and Kip Thorne, researchers who made decisive contributions to the Laser Interferometer Gravitational-Wave Observatory (LIGO) and its observation of gravitational waves.

Improved Cooling Leads to Rare Achievement in Study of Antimatter

Scientists at CERN are celebrating a rare achievement in precision physics in which collaborators on its BASE experiment measured a property of antimatter 350 times as precisely as it had ever been measured before. The result was accomplished after researchers improved cooling methods for the experiment.

Webb Selfie Focus of Critical Cryogenic Test

What appears to be a unique selfie opportunity was actually a critical photo for the cryogenic testing of NASA’s James Webb Space Telescope in Chamber A at NASA’s Johnson Space Center in Houston. The photo was used to verify the line of sight (the path light will travel) for the...

CUORE Releases First Data Collection

Researchers have released the first collection of data from the full detector of CUORE (Cryogenic Underground Observatory for Rare Events), an experiment considered to be one of the most promising efforts to determine whether tiny elementary particles called neutrinos are identical to their own antiparticles.

Manufacturers Complete Cryogenic Tank Delivery to ITER

European manufacturers have delivered the last of the 11 cryogenic tanks contracted for the cryoplant at ITER. The manufacturing of all components was undertaken by Air Liquide advanced Technologies (CSA CSM) and its subcontractors, while logistics were handled by DAHER. The ITER fusion machine will require a massive refrigerator to...

Celebrate Dark Matter Day

On October 31, 2017, institutions worldwide will celebrate Dark Matter Day with events highlighting the 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...

Regenerators

Regenerators or regenerative heat exchangers are a key component of cryocoolers such as pulse tube cryocoolers (Cold Facts, August 2014). Regenerator performance greatly affects the coefficient of performance of cryocoolers. Improvements in regenerator design and, in particular, regenerator materials have been an important factor in the improvement of the performance...

Pulse Tube Cryocoolers

The development of pulse tube cryocoolers has been a significant topic of research and development over the past 20 or so years. Pulse tube cryocoolers have a number of advantages over other types of cryocoolers and are now available commercially. In order to understand pulse tube cryocoolers, it’s best to...

Thermal Expansion

Thermal expansion refers to the change in size (length or volume) that a material undergoes as its temperature changes. In cryogenic systems this effect can be quite large and must be allowed for in the design. In isotropic materials, which include most engineering materials, the thermal expansion is the same...

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?
