Plasma bullets can be transferred across a dielectric plate if a helium jet is irradiated behind the plate. In this work, we have varied distance between the plate and the helium jet nozzle. In the case of the distance less than 20 mm, the bullets can be transfred. However, in the case of distance of 30 mm, the bullets cannot be transferred. We discuss this phenomenon together with spatial distribution of helium-purity behind the plate.
