Abstract

931,572. Ionization gauges. NATIONAL RESEARCH COUNCIL. Aug. 29, 1961 [Aug. 29, 1960], No. 31141/61. Addition to 890,920. Class 39 (1). In a magnetron-type ionization gauge the shields for preventing field emission are cylindrical auxiliary electrodes 44, 45 projecting between the anode coating 10 and the flanges 12, 13 on the cathode 11.
