Abstract

The performance of the CsI electromagnetic calorimeter to be used for the J-PARC E14 KOTO experiment for a rare decay K_L → π⁰ν ν ¯ was studied by using a positron beam from an accelerator. The energy, timing, and position resolutions for energies up to 800 MeV were measured. We also developed a new method to reconstruct the incident angle of photons based on the shower shape recorded with the calorimeter, and evaluated the method to suppress possible backgrounds for K_L → π⁰ν ν ¯ decay signals.
