WebCrookes tube, device invented by Sir William Crookes (c.1875) consisting essentially of a sealed glass tube from which nearly all the air has been removed and through the walls of which are passed two electrodes. When a high voltage is applied between the two electrodes, electrons are emitted from the cathode and are accelerated toward the anode. WebA többnyire televíziós vevőkészülékekben használt katódsugárcsövet Sir William Crookes fedezte fel körülbelül száz évvel ezelőtt.
