Show 100,000,000 Volls " In X-Ray Machine, New Electron Accelerator Is Given Credit. ' SCHENECTADY, N. Y. Two years of study and experimentation with high-voltage x-ray machines culminated here with the production' at the General Electric laboratories' of rays carrying 100 million volts 100 times more powerful than the largest industrial x-ray in use today, to-day, and the highest x-ray voltage ever obtained. The record-breaking voltage was achieved with a new -electron accelerator. ; The production of the elaborate mechanism which gave off the giant, rays for the first time, catching company officials unprepared for making a detailed announcement of the feat, was completed under the supervision of Dr. W. D. Coolidge,! laboratory director; Dr. E. E. Charl-; ton, chief of the G. E. X-ray divi-i sion, and W. F. Westendorp, his assistant. as-sistant. The actual production of the rec-i ord-breaking rays indicated the discovery dis-covery of a character of electron radiation differing from that pro- duced by machines with which pres-. ent-day scientists are familiar. For; that reason, Dr. Coolidge said there' would be no further announcements concerning the new mechanism un-' til after further study. j The operation of the electron ac-. celerator is similar to that of the transformer, used for changing the' voltage of electricity. |
