Experiment E36 at the Japan Proton Accelerator Research Complex will study the decay of stopped kaons to search for new physics beyond the Standard Model. In particular, the experiment aims to provide the most stringent test of lepton universality to date in a measurement of the ratio of the Ke2 and Kmu2 decay widths, and will simultaneously search for light new particles, such as a heavy sterile neutrino or a dark photon. The experimental setup is based on the upgraded detector of KEK experiment E246 and includes a large-acceptance toroidal spectrometer for tracking charged particles with high resolution, combined with a photon calorimeter with large solid angle. The current status of the upcoming experiment and the planned measurements will be presented.
