The Position-sensitive TES (PoST) microcalorimeter, based on a Transition Edge Sensor (TES), is a radiation detector that offers excellent energy and position resolution. In this study, we evaluated the effects of Compton-induced multiple scattering and various noise sources on detector performance for gamma-ray measurements in the several hundred keV to several MeV energy range through simulation. The energy deposition distribution within a lead absorber was calculated using PHITS, and the resulting data were used to analyze the signal response of the PoST microcalorimeter. The impacts of multiple scattering and noise on both position and energy resolution were quantitatively investigated.
