Zircon Vacuum UV Detector

MCP-based vacuum detector with a magnesium fluoride input window and a yellow-green emitting phosphor screen on glass.

The detector consists of a chevron stack of two MCPs providing operation in photon counting mode. A cesium iodide photocathode is deposited on the input surface of the first MCP to increase the UV sensitivity. The detector is intended for detection, intensity measurement and, if necessary, imaging of far ultraviolet radiation.
