Abstract :
We present the first experimental characterization of an innovative two-chips detector system for X-ray spectroscopy experiments in which stability of operation is mandatory to avoid on-line calibration procedures. The system is based on a silicon drift detector and on a charge amplifier, partly integrated in the detector chip. The design guidelines of both the “detector chip” produced on a high resistivity substrate and the “amplifier chip” designed in 0.8 μm BiCMOS technology are reviewed. The proper functionality of each of the two chips and the performance of the whole system have been experimentally verified
