New Thermometer Measures Cryogenic Temperatures at Submicron Scales
Taking the temperature of a sample can be tricky—especially in the regimes of the very small and the very cold. The smaller the sample, the greater the influence the thermometer itself may exert on the measurement. And in the ultracold regime, even tiny amounts of heat can significantly alter the...

Nanoparticles Show Quick and Easy Way to Target Cancer
Researchers have been exploring the use of injectable nanoparticles that can quickly home in on a microscopic tumor. It’s a novel technique that could pave the way for the early detection of small tumors that may not show up on traditional imaging technologies. In a study published in the October issue of...
Researchers Simplify Switching for Quantum Electronics
A quantum cousin of the Hall effect could open the door to energy-efficient electronics, better sensors, and more-powerful quantum computers. Researchers have now broken a key barrier to its practical application by controlling the phenomenon electrically, rather than magnetically, for the first time. The Hall effect, discovered by physicist Edwin...
Firefly Aerospace Awarded Multi-Launch Agreement with L3Harris
Firefly Aerospace, Inc., an end-to-end space transportation company, today announced it signed a multi-launch agreement with L3Harris Technologies for three dedicated launches on Firefly’s Alpha vehicle in 2026. With the capability to launch more than 1,000 kg to low Earth orbit, Firefly’s Alpha vehicle provides affordable, responsive, and reliable launch...

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...
Magnets
From “Superconductivity: Present and Future Applications” by the Coalition for the Commercial Application of Superconductors. Particle physics uses accelerators to recreate the conditions of the early universe in an attempt to piece together the complex puzzle of how we got to where we are today. These huge machines are used...
Energy Storage
From “Superconductivity: Present and Future Applications” by the Coalition for the Commercial Application of Superconductors. With power lines increasingly congested and prone to instability, strategic injection of brief bursts of real power can play a crucial role in maintaining grid reliability. Small-scale Superconducting Magnetic Energy Storage (SMES) systems, based on...
Astronomy
ASTRONOMY IN SPACE by Peter V. Mason, retired, Jet Propulsion Laboratory, and Visiting Associate, California Institute of Technology. Pmason@alumni.caltech.edu In thinking about the reasons to perform astronomy in space, we first consider the effect of the earth’s atmosphere. On a scale of decreasing energy, gamma rays, cosmic rays, X-rays and...
Cryocoolers
What is a Cryocooler? A mechanism that can extract heat from an object (cooler) and by doing so draw its temperature down below approximately 150 Kelvin (cryo). — (Courtesy Dr. Willy Gully) What is the difference between a Cryocooler and a Cryostat? A cryostat is any device designed to maintain...
Reliability and mounting of electronic substrates at low temperatures
I am currently working on the design of a focal plane assembly to be implemented on a small satellite (4 EMCCD detectors) to be operated at -80°C (which is not really cryogenic and likely still considered boiling hot for most of you :-). As it is passively cooled, the assembly...
Are 3D drawings included in the sale of a cryogenic plant?
I have a question concerning the 3D drawings of a cryogenic plant. The integration of the 3D drawings of a plant with the 3D main model of a new laboratory or a new facility can be a complex work that takes a lot of time. I would like to know...
Looking for a source of LOX impact testing to ASTM D2512
I have been looking for a source of LOX impact testing to ASTM D2512. I am aware of NASA and White Sands, but am looking for a commercial entity doing the work. No luck so far, even calling a lot of the folks on the CSA website. Any referrals will...
