| Abstract (en) | We describe a prototype γ-ray detector based on a metallic magnetic calorimeter with an energy resolution of 46 eV at 60 keV and a reproducible response function that follows a simple second- order polynomial. The simple detector calibration allows adding high-resolution spectra from differ- ent pixels and different cool-downs without loss in energy resolution to determine &gammay;-ray centroids with high accuracy. As an example of an application in nuclear safeguards enabled by such a &gammay;-ray detector, we discuss the non-destructive assay of 242Pu in a mixed-isotope Pu sample. |
