Since the Fukushima nuclear accident, it has become important to develop imaging sensors that have high environmental resistance under special circumstances. As an example, there is a request for high radiation resistance and high temperature operation for monitoring in nuclear reactors. Semiconductor image sensors such as CCD and CMOS have a defect in the gate oxide film and crystal structure due to the effect of radiation, so it is difficult to capture images for a long time. On the other hand, since the imaging tube uses vacuum electrons with no microstructure, high radiation resistance is expected.
In this study, we propose a high speed electron beam reading that operates by accumulating electrons as image signals. Electrons have a higher mobility than holes, so they are expected to have afterimage suppression and highly efficient carrier collection. To verify the proposed method, we attempted to image by controlling the secondary electron yield on the electron beam incident side of the photoconductive film by controlling the electrode voltage close to the photoconductive film. We evaluated the image changes when the environmental temperature of the tube was changed. |
