The world's largest x-ray, a gigantic tube operating under the impulse of 1,000,000 volts of electricity, is being exhibited by scientists at the California Institute of Technology.... The ray, which is being used in complicated scientific experiments, is so powerful that it will penetrate two inches of lead, whereas a quarter of an inch of lead has heretofore stopped the most powerful Xray . . . " Photograph and text are from a Caltech press release. At the controls are Professors Ralph D. Bennett and C. C. Lauritsen.
