A Powerful and Efficient Means of Driving X-Ray Tubes

Abstract

DURING the last few months the limitations of the present induction coil, especially as a means of driving X-ray tubes and vacuum tubes in general, have been so clearly brought before us that we have given the subject considerable attention. It is true that with some of the new forms of circuit breakers and storage batteries, an induction coil can be made to work fairly well during prolonged runs; but storage batteries are troublesome, and a break that will work on voltages ordinarily supplied for lighting is yet to be made.
