Abstract
A high-speed current transducer with fiber optic coupling for recording the ion current from the measuring electrode of the Langmuir probe of the KI-1 installation of the Institute of Laser Physics of the Siberian Academy of Sciences is described. It is proposed to use a structure consisting of a plastic optical fiber 1 mm that transmits light at 650 nm, fast IF-E91 LEDs, and an IF-D91 photodiode for coupling. The results of laboratory testing of this high-speed converter with old one based on a AOD129A diode optocoupler under conditions close to the working conditions are compared.
