Abstract:	^{Precision muonic x-ray measurements in light exotic atoms are becoming possible thanks to advances in quantum-sensing technology. These measurements enable significantly improved determinations of nuclear charge radii, which are essential for testing fundamental physics and exploring potential new physics. Our new collaboration,}^QUARTET^{, aims to improve the charge radii of light nuclei by an order of magnitude. This is made possible by deploying}^{magnetic microcalorimeter}^{detectors which possess high quantum-efficiency and exceptional resolution for determining energies of x-ray photons. In a recent experiment, we measured low-lying transitions in muonic 9Be, which are particularly sensitive to nuclear structure and finite-size effects. In this talk, I will present my ongoing analysis and results towards a significant improvement in the charge radius of 9Be.}
