Physicists at MIT have developed a new tabletop particle detector that is able to indentify single electrons in a radioactive gas. The gas used in the experiment decays and as it decays, it gives off electrons. The tabletop detector then uses a magnet to trap the electrons inside a magnetic bottle.

An antenna on the detection is then able to pick up very weak signals emitted by the electrons that can then be used to map the precise activity of the electrons over several milliseconds. The MIT researchers were assisted in developing the device by researchers at Pacific Northwest National Laborat...
