High-Resolution X-ray Spectroscopy of Light Muonic Atoms
The low-lying energy levels of muonic atoms are highly sensitive to nuclear structure due to the strong overlap of the muon wavefunction with the nucleus. The energy of the muonic 2p-1s transition allows the determination of the nuclear charge radius, an essential quantity for establishing reliable nuclear models. The QUARTET collaboration aims to achieve an improvement by more than an order of magnitude in the precision of nuclear charge radii for light atoms from Li to Ne. This thesis focuses on the detector development within QUARTET for high-resolution X-ray spectroscopy of muonic atoms. A dedicated MMC-based detector array was designed, fabricated, and characterized. A cryostat sidearm was designed and assembled, a precise ADC calibration was established, and a data analysis library was developed. Two successful muon-beam measurements using Li, Be, and B as target materials were conducted. The results demonstrate the feasibility of QUARTET for significantly improving the accuracy of nuclear charge radii for light nuclei.
