A CONDENSER-TYPE ACCELERATOR BEAM-CURRENT INTEGRATOR WITHOUT RELAY USE
D. Jovanovic, R. Ilić · VinaR (Institute of Nuclear Sciences "Vinča") · 1961
The paper describes a current integrator covering the range from 10⁻² to 10⁻⁷ A with an accuracy of 1 %. The reliability and the accuracy of the instrument are improved by using transistors and vacuum tube diodes instead of discharging relays, as well as by using transistors in the circuits which determine the charging and discharging levels of the charging condenser.
