Abstract
A proto type multianode photomultiplier tube incorporating a chevron type MCPs electron multiplier and 400 multi anodes was developed for high speed image pick-up at low light levels such as in detection of rings of Cherenkov light. The diameter of and mean spacing of each anode are 0.3mm and 0.65mm respectively in a rectangular array of 16mm×12mm. The MCP used in the tube were fabricated at HTV and had 24.9mm diameter, 20mm useful diameter, 15μm pore diameter and 45 length to pore diameter ratio. Electron multiplication and dark current for each MCP were about 104 and 1pA at 1000v respectively. 0.6mm spatial resolution over anode surface and about 600psec rise time of output signal were obtained.Keywords
