FEDS Want Backpack Radiation Detectors That Don’t Use Rare Gas
The government is looking for backpack-based radiation detection systems that don’t require an increasingly rare isotope of helium traditionally used in such devices. The Defense and Homeland Security departments want to test the radiation detectors against current standards as part … Continue reading

Notes from the Editors: Bargaining for a Better Helium Deal
Without liquid helium, scientists couldn’t cool the magnets at particle accelerators, medical researchers would have to shut down their MRI machines, and most known superconductors would never have been discovered. But per-liter costs of the cryogen have been creeping up … Continue reading

On the Use of Helium-filled Soap Bubbles for Large-scale Tomographic PIV Wind Tunnel Experiments
The use of particle image velocimetry in wind tunnels has evolved from experiments done at moderate scale (typically 10×10 cm2) up to large scale ones both for aeronautical as well as automotive applications (50×50 cm2). Considering three-dimensional techniques, tomographic PIV … Continue reading

Liquid Helium Program to Test Leveraged Buying Power of Small-scale Users
The American Physical Society (APS) and the American Chemical Society (ACS) have announced the formation of the Liquid Helium Program, which aims to ensure that academic researchers with federal grants have the opportunity to purchase small quantities of liquid helium … Continue reading

Hunt For Helium Shifts From Amarillo To Qatar
For 50 years a vast aquifer in the heart of the Texas panhandle has held as much as 30 percent of the word’s helium reserves, acting as a safety valve that buoys supplies when the global market is interrupted. The … Continue reading
