Details
A Crookes tube is an early experimental electrical discharge tube, invented by British physicist William Crookes and others around 1869-1875, in which cathode rays, that is electrons, were discovered. An evolution of the Geissler tube, it consists of a partially evacuated glass cylinder of various shapes, with two metal electrodes at either end. When a high voltage is applied between the electrodes, electrons travel in straight lines from the cathode to the anode. It was used by Crookes, Johann Hittorf, Juliusz Plücker, Eugen Goldstein, Heinrich Hertz, Philipp Lenard and others to discover the properties of cathode rays, culminating in J. J. Thomson's 1897 identification of cathode rays as negatively-charged particles, which were later named electrons. Crookes tubes are now used only for demonstrating cathode rays.
