Development of Large area position sensitive MCP detector at Rare RI Ring

抄録

A large-area position-sensitive and high-resolution time-of-flight detector for research on mass measurements of exotic nuclei is planning to be developed at Rare RI Ring(R3) in RIBF, RIKEN Nishina Center, Japan. Advances in nano-technology and material science, realized by recent innovations in data processing and microelectronics, give us an opportunity to apply the basic concept of micro-channel plate detectors to the development of large- area secondary electrons detectors with inherent good position and time resolution. The main purpose of using this detector is to install it in the storage ring to monitor the position and turn-by-turn time of flight(TOF) of a single heavy fully ionized ion circulating in the storage ring. We have investigated the recently used MCP detectors for TOF and position monitor utilization and find a best way to build a optimum MCP detector in the storage ring, Rare RI Ring. We have finished the simulation and design of the MCP detector. For this report, the simulation results and principle of design will be reported.
