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.

Dilution Refrigerators

Dilution refrigerators are a common technique for reaching temperatures below 1K, particularly where continuous cooling at these temperatures is required. Helium exists in two stable isotopes: 4He and 3He. Naturally occurring 3He is extremely rare, constituting less than 1 part per million of helium gas. However, 3He can be manufactured,...

Oxygen Deficiency Hazards

Oxygen Deficiency Hazards (ODH) are a significant safety issue in cryogenic facilities. ODH occurs when inert gases such as nitrogen, helium or argon displace room air and thus lower the percentage of oxygen in the space below that required for human life. OSHA defines an area as oxygen deficient if...

Kelvin Temperature Scale

The Kelvin temperature scale is the principal temperature scale used in cryogenics and science. The kelvin is also one of the seven base units in the Système International d’Unités (SI) and is the unit of thermodynamic temperature. Thermodynamic temperature is a fundamental physical quantity (like mass, length or electrical current)...

Bose-Einstein Condensate

A Bose-Einstein condensate, first proposed in 1925 by Albert Einstein based on work done by Satyendra Nath Bose (the same Bose from whom the term boson is derived), is a super-cold state of matter in which almost all of the individual atoms have “condensed” down to the lowest possible quantum...

Cold Technology for Pest Control

While it does not reach temperatures cold enough to be called cryogenic, carbon dioxide snow is at the heart of a new way of dealing with unwanted pests. It utilizes a quick freezing process that takes advantage of the properties of carbon dioxide snow and has a number of benefits...

Cryogenic Finishing

The following 3 articles discuss the uses and procedures of various type of cryogenic finishing. 1) By Robin A. Rhodes, Cryogenic Institute of New England, Inc. rrhodes@nitrofreeze.com Cryogenic Deflashing is employed to remove undesired residual mold flash that remains on molded parts after they are removed or ejected from the...

Definition or max temp which defines “cryogenic”?

Please help me with a definition: I am calculating material and fabrication costs for a quote for a hydrocarbon meter station.

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.
