description: This work is devoted to the study of the influence of gas-dynamic flow on the transport 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. Measurements are made on a concentric collector As a result, a comparison of the efficiency of ion beam transport in an ion source with a corona discharge for the antielectrode aperture due to the pulling electric field and gas-dynamic flow is made. The gas dynamic flow causes a slight compression of the beam in the atmospheric region of the region and radically changes the situation when the beam passes through the nozzle aperture. As a result, the maximum current registered on the collector increases by 3 times( in relation to the maximum current during extraction by an electric field). 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.
