Microchannel plates (MCP) are widely used in different fields of science and technology. They have good operational parameters, such as short response time (<1 ns), good spatial resolution, sensitivity up to single electron mode, high radiation hardness, immunity to magnetic fields. We propose a new kind of MCP based on an anodic aluminum oxide substrate formed by electrochemical oxidation of aluminium. This work presents preliminary results on Al2O3 based MCPs. A research program is proposed which includes studies of the electrophysical properties of this MCPs in function of various geometric parameters (thickness, channel diameter to length ratio, effective surface, etc.).
