The efficient detection of low-energy X-rays at the keV level with best possible energy resolution requires application silicon drift detectors (SDDs) and advanced specific integrated circuits (ASICs). Their widespread use in material sciences, alongside dedicated basic science projects, has long been restricted to single, selected SDD elements working low temperatures. This is because limits incurring quite elaborated planar technology production process need reach very leakage current...
