:Development of electronics and X-Ray spectroscopy instrumentation for synchrotron applicationsAbstract:
The increase of interest in X-ray Nanoprobe (XNP) and the rapid growth in brilliance of synchrotrons push the development of X-ray detection systems able to cope with their high-rates demanding requirements. Nowadays, multichannel X-ray detectors in synchrotron applications are very widespread. However, most of multichannel detection systems are usually obtained combining single-element Silicon Drift Detectors (SDDs). The main drawback of such an approach is the large dead area among elements; thus, an emerging trend in development of SDDs is moving to a monolithic configuration which allows to minimize source-detector distance and increase solid angle. In my PhD acttivity, I analyze the property of monolithic SDD arrays with different wafer thicknesses. In addition to performance as energy resolution, I investigate charge sharing phenomena among contiguous elements and the behavior of the charge collection at the anode through simulations and experimental results. I also design and develop instruments to host the detection modules in order to test them in synchrotron beamlines.
