Development of micro-channel plates on a basis of aluminum oxide

Micro-channel 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 and immunity to magnetic fields. We propose a new kind of MCP based on an anodic aluminum oxide substrate formed by electrochemical oxidation of aluminum. This work presents preliminary results on Al2O3-based MCPs. A research program is proposed which includes studies of the electrophysical properties of these MCPs in function of various geometric parameters (thickness, channel diameter-to-length ratio, effective surface, etc.).
