Description
We have been developing a Cherenkov ring-imaging counter, named TOP counter,
as a particle identification device of Belle-II detector for super B-factory
at KEK. In this presentation, we show the R&D status of TOP counter prototype
development. We have performed the beam test using 2m long quartz radiator
and MCP-PMTs, and evaluated the number of detected photons, time resolution
and chromatic effects.
We develop the square-shape MCP-PMT with Hamamatsu photonics, to obtain the
enough lifetime under the Belle-II environment. We improved the lifetime
of the quantum efficiency by changing the internal structure and production
process.
