R. BERRY 1 has recently directed attention to the use of helium in place of argon in a conventional argon detector. All the rare gases should behave in the same manner as argon, that is, collision of ...

Physicists propose a dark matter detector that would use superfluid helium to explore mass ranges for dark matter particles thousands of times smaller than current large-scale experiments. Physicists ...

THE development of high-sensitivity detectors for the chromatographic analysis of gaseous mixtures is of importance in the determination of substances present in very small amounts. A sensitive ...

Mass spectrometers can now be operated at pressures in the proximity of those applied in most plasma processing systems due to the availability of particle detectors capable of being used at pressures ...

Scientists are building on decades of sensor work to invent tiny detectors that can sniff out everything from explosives and biotoxins to smuggled humans. Sandia National Laboratories scientists are ...
