Abstract:
An image intensifier tube includes a collimator having multiple channels for receiving electrons from a photocathode layer, and a microchannel plate (MCP) having multiple channels for receiving electrons from the collimator. An ion barrier film (IBF) is disposed on top of an input side of the MCP, in which the IBF includes a small amount of conductive material. The IBF may include alumina doped with chromium oxide, or manganese oxide, or any other conductive material. The small amount of conductive material includes 1% to 5% of conductive material in a layer of non-conductive material.
