Description
PIONEER aims to measure the charged-pion branching ratio to electrons versus muons (R$_π$) with about 15 times better precision in its first phase and the pion beta decay, $π^+ → π^0e+ν(γ)$, with 3 to 10-fold improvement in sensitivity in the next step. The PIONEER detector is designe1d to measure these reactions with great precision by employing a 5D active target and a high-resolution calorimeter. One of the calorimeter designs is based on liquid xenon technology with scintillation light readout. We present the PIONEER LXe calorimeter R&D status as well as its design.
