摘要

In this study, a single-mask triple gas electron multiplier (GEM) prototype, operated with an Ar/CO \(_2\) 2 (70/30) mixture, was characterised using a \(^{55}\) 55 Fe X-ray source. Detector efficiency, gain, energy resolution and stability under high radiation were investigated, with particular focus on efficiency stability, providing insights into reliable GEM operation.
