description: The topic of the final qualifying work: "Experimental study of the process of ion current transportation from a corona discharge ion source to the first stage of the gas-dynamic interface of a mass spectrometer". This work is devoted to the study of the influence of the gas-dynamic flow and the electrostatic field of the focusing system on the transportation of charged particles through the nozzle of the first stage of the differential pumping system of the gas-dynamic interface of the ion source at atmospheric pressure. The paper compares the efficiency of ion transport in a standing gas and from the atmospheric pressure region to the forevacuum region with and without a focusing system. Measurements are carried out on a concentric collector. As a result of the work, a comparison was made of the efficiency of transporting an ion beam in an ion source with a corona discharge over the antielectrode aperture due to the pulling electric field, gas dynamic flow and the influence of the electrostatic field of the focusing system. Due to the influence of the gas-dynamic flow and the electrostatic field of the focusing system, it was possible to increase the number of ions passing behind the collector. As a result, the maximum current recorded on the collector increases by 13 times (relative to the maximum current during extraction by an electric field) and by 2.5 times (relative to the maximum current during extraction by a gas-dynamic flow). The obtained data can be used to develop a focusing ion-optical system located in the atmospheric region of the gas-dynamic interface of the mass spectrometer.
