The british physicist joseph john (j j) thomson (1856-1940) performed a series of experiments in 1897 designed to study the nature of electric discharge in a high-vacuum cathode-ray tube, an area being investigated by many scientists at the time thomson interpreted the deflection of the rays by electrically charged plates and magnets as.
