ee Fig. 6), all the ordinary phenomenaof a discharge tube can be reproduced by means of quitesmall potentials—100 volts or less between the cathode andanode. The hot lime emits torrents of corpuscles and thepencil of cathode rays, owing to their low speed (see p. 12),produces vivid luminosity in… … Fig, 6.—A discharge tube with a Wehnelt cathode, displayisg the repnWonof the cathode rays by a negatively charged plate. an ordinary discharge tube; e.g. with 50 volts, the velocity= 4-2 X 10* cms. per sec.
