Abstract:

A systematic study is being conducted of bombardment-induced-conductivity BIC materials which can be used to demonstrate the feasibility of a meshless storage tube. Criteria were established for the BIC characteristics which a dielectric must exhibit to switch and maintain the voltage drop across an electroluminescent EL layer. It was found that the conductance of the BIC dielectric before bombardment must be less than the susceptance and that the conductance after bombardment must be at least ten times the susceptance. The circuits and techniques to measure both the instantaneous ac BIC response as well as the sustained BIC response to pulsed electron bombardment were completed. Data on 12-micron zinc sulfide films were obtained for the sustained BIC response and ac values of the conduction ratio. A simple theoretical model was constructed from the data. On the basis of this model, it appears that the formation of space charge in the volume of the dielectric plays a major role in the BIC effect. The magnitude of the sustained BIC currents was found to vary from one film to another. Author
