INFLUENCE OF FEATURES OF THE ELECTRIC FIELD IN THE DIAPHRAGM SYSTEM ON THE TRANSPORTATION OF THE FLOW OF CHARGED PARTICLES AT ATMOSPHERIC PRESSURE

The results of numerical simulation of the ion-optical scheme of ion transport at atmospheric pressure are presented. The possibility of efficient transport of ions in the system under consideration with an increase in the local curvature of the equipotential lines of the electrostatic field in the vicinity of the nozzle by shaping (changing the shape) of this electrode is shown. Shaping the nozzle allows to increase the value of Icoплo by approximately 1.6 times. Taking into account the gas-dynamic effect on the transport of the ion beam through the nozzle makes it possible to obtain the values of the transmission by 70% higher.
