New Particle Detector That Can ‘See’ Individual Electrons Developed By Scientists

Scientists at the Massachusetts Institute of Technology (MIT) have developed a new tabletop instrument that can detect individual electrons in a radioactive gas. The development of the new particle detector is being considered as a major step toward measuring the mass of a neutrino, a particle smaller than an atom and with no electrical charge.

As a radioactive gas decays and emits electrons, the detector -- created as part of an experiment dubbed “Project 8” -- uses a magnet to trap them in a magnetic bottle. A radio antenna then catches very weak signals released by the electrons, which, according to scientists, can be used to accurately...
