RESISTIVE SEA FOR CAMERA TUBE EMPLOYING SILICON TARGET WITH ARRAY OF DIODES

摘要

A camera tube employing a silicon target with a diode array which is covered with a resistive layer or sea on the side facing the electron beam. The resistive sea consists of a layer of bismuth oxide which protects the silicon target from damage by x-rays while minimizing charge build-up on the insulating layer between diodes which would otherwise prevent beam landing. The resistive sea is covered by a very thin layer of cadmium telluride which stabilizes the Bi2O3 layer and improves its beam acceptance properties.
