The 10830 Angstrom Helium Line Among Evolved Stars in the Globular Cluster M4
Helium is a pivotal element in understanding multiple main sequences and extended horizontal branches observed in some globular clusters. Here we present a spectroscopic study of helium in the nearby globular cluster M4. We have obtained spectra of the chromospheric … Continue reading

Helium ‘Balloons’ Offer New Path To Control Complex Materials
Researchers at the Department of Energy’s Oak Ridge National Laboratory have developed a new method to manipulate a wide range of materials and their behavior using only a handful of helium ions. The team’s technique, published in Physical Review Letters, … Continue reading

Separating Compressor Oil from Helium
Compression of helium by an oil-sealed rotary screw compressor releases as much as 4,000 parts per million by weight (ppm) of liquid and vapor oil impurities into the helium gas. Any helium gas used for cryogenic applications must contain less … Continue reading

Measurement of Helium in Fossil Water
Helium generated deep within the Earth’s mantle eventually reaches the Earth’s crust and surface carried in solution from aquifer-gathered fossil water, the concentration level providing a key indicator of the rate of helium generation and transport. Hiden Analytical (UK) manufacture … Continue reading
