Abstract
Extensive efforts at INFN Pisa have focused on optimizing a gas detector for low pressures down to 100 mbar. MICROMEGAS technology, with its tunable avalanche volume, is inherently suited for these conditions. However initial standard simulations predicted low gain at these pressures. An extensive test campaign with X-ray sources and refined simulations based on experimental results have provided a better understanding of the detector's performance across different gas pressures. © 2024
