Cold Facts Digital – The go-to place for Cryogenics and Superconductivity

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...

Young Professionals 2020: The Next Generation in Cryogenics Part 1

Young Professionals 2020 Part 1 introduces outstanding young professionals (under 40 years of age) who are doing interesting things in cryogenics and superconductivity and who show promise of making a difference in their fields.

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...

Magnetic Levitation

From http://www.superconductors.org. Magnetic-levitation is an application where superconductors perform extremely well. Transport vehicles such as trains can be made to “float” on strong superconducting magnets, virtually eliminating friction between the train and its tracks. Not only would conventional electromagnets waste much of the electrical energy as heat, they would have...

Superconductivity

From Superpower website. History of Superconductivity Superconductivity was discovered in 1911 by the Dutch physicist, Heike Kammerlingh Onnes when he was able to liquefy helium by cooling it to 4 Kelvin, or -452°F. This enabled him to cool other materials close to absolute zero and investigate their electrical properties. He...

Medical Applications of Cryogenics

Neutron Therapy Cryogenics is at the heart of nuclear accelerators. Accelerators such as Fermilab’s Tevatron make neutron therapy for cancer possible. From Fermilab Today 4/20/09: Fermilab currently offers neutron therapy. But staff at Fermilab designed and built the proton accelerator used by the nation’s first hospital-based treatment center to use...

Nuclear Physics

Al Zeller National Superconducting Cyclotron Lab (NSCL) at Michigan State University zeller@nscl.msu.edu Cryogenics has a long history in nuclear physics. The technology has its origins in the use of cold traps for maintaining a vacuum, which is required to prevent beam loss and for generating high voltages used in acceleration....

Thermal shock on steel cylinder when dropped into liquid nitrogen

We are a research team at the University of South Florida, studying the “thermal shock” on a steel cylinder when it is dropped into liquid nitrogen. We want to make sure that the thermocouple does not get influenced by the surrounding LN2. Any advice?

Getter materials to absorb out gassed materials?

Here’s one for the scientists: We would like to sell vacuum insulated pipe for high temperature fluid applications. Are there any good getter materials that we can place in the vacuum space of our VJP to absorb outgassed materials at elevated temperatures?

Data on Carbon Fibres Reinforced Plastic at temperatures between 4 and 300K.

I am looking for data on Carbon Fibres Reinforced Plastic at temperatures between 4 and 300K. I would appreciate it if someone could give me some hints on where to find it.
