Abstract
1,249,795. Supply systems for X-ray apparatus. CHIRANA MODRANY NARODNI PODNIK. 22 Jan., 1970 [27 Jan., 1969] No. 3250/70. Heading H2H. [Also in Division G1] In various types of X-ray analysis, the X-ray tube 5 is supplied with a high D.C. voltage modulated with a small A.C. voltage. The D.C. voltage is obtained from an A.C. supply across which is connected autotransformer 10, rectifying circuit 12 and smoothing capacitor 13. Meters 14, 16 monitor the tube voltage and current. The A.C. modulation is via autotransformer 21.
