The CUORE Underground Experiment Narrows the Search for Rare Particle Process

In an underground laboratory deep beneath a mountain in Central Italy, an array of crystals, chilled to within a hair of absolute zero has been steadily compiling one of the most precise measurements to date in pursuit of a rare particle process. If it is proven to exist, this process...

World’s First Hydrogen-Powered Superyacht is Here and It Is a Beauty

The world's first hydrogen-powered superyacht was unveiled last week at the Monaco Yacht Show and it made quite an impression. The model of the 367-foot yacht was the pinnacle of luxury and sophistication. The miniature model was presented by a Dutch firm called Sinot Yacht & Architecture Design. The ship,...

Development of an ISO Standard for the Testing of Insulation Materials under Cryogenic Conditions

The mission of the International Organization for Standardization (ISO) is to create reference standards that identify requirements, specifications, guidelines and characteristics that can be used consistently by manufacturers and users to ensure that materials, products, processes and services are fit for their purpose. During the past several years, a group...

Securing Flight’s Clean Future with Cryogenics and Superconductivity

Joshua Feldman, a graduate student in the University of Illinois at Urbana-Champaign’s Haran Research Group, headed by Professor Kiruba Haran, is currently working to solve a rather lofty problem… literally. He and the Haran team are addressing the uncertain outcome of airline travel in an envirocentric future by developing a...

LUX-ZEPLIN Cryostat Installed at Sanford Underground Research Facility

On October 21, crews at the Sanford Underground Research Facility (SURF) in South Dakota strapped the cryostat containing the central component of LUX-ZEPLIN (LZ), the largest direct-detection dark matter experiment in the US, below an elevator and slowly lowered it 4,850 feet down a shaft formerly used in gold-mining operations—final...

The Coolest LEGO in the Universe

For the first time, LEGO has been cooled to the lowest temperature possible in an experiment which reveals a new use for the popular toy. A team of ultra low temperature physicists at Lancaster University decided to place a LEGO figure and four LEGO blocks inside their record-breaking dilution refrigerator....

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...

Looking for the thermal conductivity of the high density polyethylene (HDPE) between 1.9 and 10K

I am looking for the thermal conductivity of the high density polyethylene (HDPE) between 1.9 and 10K (or even up to higher temperatures). The best would be to have these data for the HDPE material which sold by the CERN shop, which has a density of 0.95 g/cm3. Pier Paolo...
