New tabletop detector 'sees' single electrons
Magnet-based setup may help detect the elusive mass of neutrinos
23-Apr-2015 -
MIT physicists have developed a new tabletop particle detector that is able to identify single electrons in a radioactive gas.As the gas decays and gives off electrons, the detector uses a magnet to trap them in a magnetic bottle. A radio antenna then picks up very weak signals emitted by the ...
