ABSTRACT:
Insulating crystals are coated on a metal mesh of a storage tube and give rise to a hysteresis effect with respect to the passage of flood electrons through the metal mesh, the hysteresis effect being caused by the persistent polarization of the insulating crystals when an electric field has been applied and the depolarization of the crystals due to the irradiation of an electron beam having an energy which is large enough to penetrate through the negative field produced by the persistent polarization. The clean surface of the insulating crystals, which contains recombination centers of electrons and holes and the deep traps of electrons and holes, is an essential feature of the insulating crystals and are necessary for the hysteresis effect with respect to the passage of the flood electrons through the metal mesh.
