A multi-wirescanner for diagnostics of ionizing particle beams (e.g. both non-relativistic and ultra-relativistic charged particles; X-ray and gamma photons) is proposed and discussed in the paper. The scanner is based on measurement of yield of characteristic X-rays generated during the particle interaction with the wires made of different materials. The proposed scanner is developed and tested on the beam of electrons with energy of 40 keV. The quasimonochromatic characteristic X-rays and continuous background are clearly identified. The results of measurements of the transverse size, emittance, position and direction of beam propagation are presented and discussed.
