Outline of Final Research Achievements

The curve MCP with its radius of 80mm has been developed. Three curved MCPs are assembled with the position sensitive resistive anode (RAE). We have conducted the HV test inside the vacuum chamber and simple optical test has also made. Both of the results are successful.
