Muonic atoms are an outstanding tool to study short range muon-nuclear interactions and to probe various nuclear moments. The muX experiments deploys a high-purity germanium detector array at the Paul Scherrer Institute in Switzerland to measure the muonic X-rays which are emitted during the formation of a muonic atom. In addition, novel gas-targets are deployed enabling a precise measurement of the characteristic X-rays with a target of only a few micrograms. The experiments aims to measure transitions of interest for atomic parity violation, and to determine the charge radius of radioactive isotopes such as $^{248}$Cm and $^{226}$Ra.
