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. WebDeveloped by William Crookes to investigate electrical discharges in gas. Although it is not certain what type of tube Rontgen was using when he discovered X-rays, this is the type of tube most commonly assumed to be involved. The flat disk at the left end is the cathode while the electrode in the short side arm at the bottom is the anode.
