| Show New N w Cathode Ray Tube Operating On Volts Is Perfected NEW YORK Feb 16 15 AP AP The The possibility of construction of ap apparatus apparatus ap ap- which will produce the fie beta bet and gamma rays ray of radium is i. held forth by Dr W. W D D D. Coolidge assistant director of the research laboratory of the General Genral Electric company in announcing development development develop develop- ment of a new superpower cathode ray tube tubo operating on volts The previous limit of power had been volts volta announcement was made at ata ata a a. meeting of ot the American Institute InU tute cute of l Electrical engineers where Dr Coolidge received receded the Edison medal for tor hi his hi contributions contribution to Incandescent incandescent In In- I I candescent lighting and the X FASTEST SPEED I The new tube Is ia a a. three three-In three ne ne arrangement of the Q MH volt 0 volt cathode ray tube A cuaco ar arrangement arrangement at ar- expels Expel l electrons n. n At nt the tho I rate of ot 17 1000 miles mile a H second which 1 is III the fastest man made made mado I p speed d ever at attained 1 It is I. times faster taster than th the aped of oC a bullet shot hot from Irom a standard army I rifle rICh This Thin open opens a vista of or alluring scientific possibilities said mild Dr I Coolidge in explaining the Aho sectional principle upon which the then new n nl w tube tubo ia Is built hullt It has hili tantalized i us UI for lor rea years ear to think that we couldn't pro produce in fn the laboratory I just sas a as high bleb speed electrons electron a IU as the I I highest velocity beta rays ray of ot radium ra- ra ra radium and jut just as a. penetrating radiation radia redla- tion tiona a as aa the shortest wave length gamma ray rays from radium AccordIne AccordIng Accord- Accord leg Ing to tu Sir Ernest Ernut Rutherford rd we n need only a n. little more than twice the voIla voltage which we have ban already employed to produce X X-ra X ray X-ray raya a as penetrating a as the most mOlt penetrating gamma rays ray from radium and about volta volts to produce a as high speed as 8 beta Mia ray rays EXPERIMENTS START The volt tube which Dr Coolidge demonstrated in 1924 In produced produced pro pro- enormous streams of high JIh speed peed electrons electron which changed I.
