Description
Spectroscopy of muonic hydrogen ($\mu$p) atoms allows for precise investigations of the proton’s electromagnetic structure. At PSI we want to measure the groundstate hyperfine-splitting of muonic hydrogen, from which the Zemach radius of the proton can be deduced. The experiment will use a new detection scheme which is based on the diffusion of laser-excited $\mu$p atoms inside a gas cell filled with $\text{H}_2$. Monte Carlo simulations of the $\mu$p diffusion process help to develop constraints on various parameters of the experimental setup and to estimate the sensitivity of the measurement. This poster presents the detection scheme of the hyperfine-splitting experiment and outlines the deployed Monte Carlo diffusion studies.
