Specialized sharp-focus sources of bremsstrahlung are considered to be crucial for high-energy tomography. The quality of the obtained tomograms is closely related to the size of the source, which is typically required to assess the resolution of industrial tomographs. In this paper, we have experimentally investigated the technique to reduce the focal spot size in the betatron through the decreased velocity of electron displacement onto a standard target. The results of the experiment showed that the decreased radial velocity of electron displacement onto the target significantly reduces both the horizontal and vertical dimensions of the focal spot.
