Abstract: The pinhole camera technique is used for obtaining images of ion emission sources in the micropinch discharge plasma. The region serving as the source of the most intense ion emission is $\sim$ 3 mm long in the direction of the discharge axis and $\le$ 1 mm in transverse size. The image of the emitting region obtained for observation in the axial direction apparently displays traces of action of the magnetic field of the discharge current on the directional pattern of the ion flow.
