The effect of the gas flow to the ion transport from the atmosphere to the forevacuum region of the is determined experimentally. Experimental volt-ampere characteristics of the ion flow carried by the gas-dynamic flow behind the nozzle are obtained. It is shown that the fraction of the ion current passing through the nozzle under the influence of the gas flow can be increased several times in relation to the current value due only to the extraction by the electric field. In this case, depending on the magnitude of the electric field penetrating beyond the skimmer, the current is redistributed between the nozzle and the collector. It was found that, under the experimental conditions, the entire ion flux reaches the movable collector at a distance of up to 15 mm at a field strength of 200 V / cm. The diameter of the ionic component of the flow is 1.5 mm. The ion motion in a gas is simulated for conditions close to the experimental ones. Developing research findings, it is possible to consider systems for transporting ions further to the analyzer.
