First Instrument Delivered for Jupiter Icy Moon Explorer

The first instrument to fly on ESA’s Jupiter Icy Moon Explorer, or "Juice," has been delivered for integration onto the spacecraft this month. Juice is the first large-class mission in ESA's Cosmic Vision 2015–2025 program. With launch scheduled in 2022, it will arrive at Jupiter in 2029 to perform detailed...

SpaceX’s Starship SN1 Explodes Under Cryogenic Testing

The SN1 was undergoing liquid nitrogen (LN) testing when clouds of vapor appeared underneath. A split-second later, the system exploded, lifting the whole craft a few meters into the air. The stainless steel LN tank rapidly imploded and released more vapor from the top of the craft. No fire was...

Lancaster Team Tests LEGO® as Superior Sub-Kelvin Insulator

The Ultra Low Temperature Physics Group at Lancaster University in the UK has achieved the record for coldest LEGOs in the universe by cooling the plastic toys to 4 mK in early December. Dr. Dmitry Zmeev and PhD student Joshua Chawner tested the properties of four LEGO blocks and a...

Argonne Upgrades Enable Next-Generation Experiments

Building 203 looks unassuming, but behind—and beneath—its brick exterior, researchers are performing advanced experiments and developing support systems to answer some of physics’ biggest questions. In January, Cold Facts toured the physics building at Argonne National Laboratory (CSA CSM) in Lemont IL to learn more about the ongoing upgrades from...

Clean Energy Future: The Future is Getting Colder

From the developments in cryogenic applications over the last 20 years, we can see that the world in its technological workings is getting colder. But really, the world has been getting colder for the last 150 years as advancements in mastering cold have made steady progress. Liquid air for energy...

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...

Food Processing

Cryogenics and Food The industrial gas industry provides a host of products and services related to food. The various gases have useful and sometimes fascinating applications in food industry. “The food industry is not a homogenous industry. The needs of customers processing hamburger vs. poultry vs. strawberries vs. seafood, for...

Primary Standards

Elie K. Track Hypres, Inc. elie@hypres.com http://www.hypres.com/ Primary standards involve the exact definition and realization of units of measurement for various quantities, time, length, mass, voltage, resistance, current, etc. International agreements based on the latest scientific knowledge define those units, and their realizations vary depending on the unit itself. For...

Shrink Fitting

Robin A. Rhodes Cryogenic Institute of New England, Inc. rrhodes@nitrofreeze.com Shrink fitting, (or “compression fitting” as it is sometimes called), is a method used to insert a pin or bushing into a housing or other assembly requiring an extremely tight tolerance fit. It can be used as an alternative to...

Telecommunications

From the Winter 2004 issue of Cold Facts magazine The recent M-Calc IV — 4th Industry Assessment workshop discussing military and commercial applications for low-cost cryocoolers, held in November in San Diego, highlighted progress being made in cryogenics as applied in telecommunications. The reliability and long lifetime of projects now...

Sealant Adhesive KAE 89?

Can you give me contact details for the manufacturer of a “sealant Adhesive” KAE 89? It is a vapor stop, used on insulation covering LNG carrying conduits. This is a suggested alternative to Foster 90-66. Do you have details of any other alternative products for this application?
