Development of semiconductor glass microchannel plates

The properties of the semiconductor glass microchannel plates (MCPs) are described and compared with traditional glass MCPs. The preparation technique is presented in detail. Moreover, the approach for developing microchannel plates made of semiconductor glass is investigated. The semiconductor glass microchannel plates, whose aperture is 20μm and the external diameter is 12mm, were fabricated. The gain, scintillation noise and imaging properties of MCP samples were tested with UV optoelectronic system. The experimental results show that the semiconductor microchannel plates can be fabricated with semiconductor glass materials.
