| Abstract: | We report the results of experiments on secondary penetrating radiation produced when primary x-ray beams from a solid-state cathode interact with targets made of various materials. The experiments were carried out in a high-current glow discharge device1 with various gases (H2, D2, Kr, Xe) and metal cathode samples (made of Al, Sc, Ti, Ni, Nb, Zr, Mo, Pd, Ta, W, or Pt). The targets are shields made of various foil materials (Al, Ti, Ni, Zr, Yb, Ta, and W) with a thickness of 10–30 µm. The target samples were mounted at a distance of 21 cm, and 70 cm, from the cathode. A scintillation detector using a photomultiplier was used to record the secondary radiation. In these experiments, recording of the radiation time history was carried out just before, and after, the discharge current pulses (with no discharge current). It was shown that the secondary radiation consisted of fast electrons. |
