A New Tracking Algorithm Based on Cellular Automaton Methods for MUSE Experiment*

The MUon Scattering Experiment (MUSE) aims to simultaneously measure the proton radius through e^±p and μ^±p elastic scattering and thus extracts insight into the proton radius puzzle. It is carried out at the Paul Scherrer Institute (PSI), using the PiM1 secondary beam line. The MUSE apparatus involves a large-acceptance, non-magnetic detector system. The Straw Tube Tracker (STT) detector is a part of the apparatus that measures the trajectories of the scattered particle. These trajectories are crucial to scattered event reconstruction.

A new tracking algorithm based on the cellular automaton method modified for the MUSE apparatus is devised to ascertain the reliability of recent reconstruction and the precision of physics analysis. In this presentation, an overview of the cellular automaton method will be given. Details of the algorithm itself and the challenges of implementation will also be discussed.
