Multi-Anode Linear SDDs for High-Resolution X-Ray Spectroscopy. Charge Confinement and Integration of Read-Out Electronics

摘要

Radiation detectors are used in a variety of fields to sense X-rays and y-rays, visible, UV and IR photons, neutrons or charged particles. With their help, advanced medical diagnostics can be performed (e.g. X-ray radiography, computed tomography, fluoroscopy), material research can undergo a rapid development (e.g. X-ray microanalysis, X-ray diffraction, Mauer spectroscopy and element imaging), space and its evolution (astronomy and astrophysics) can be explored through observation of X-rays and y-rays emitted by astronomical objects, etc. Semiconductor detectors, with silicon being the leading material, are used in many of the above mentioned applications. This thesis describes the development of a special type of silicon detector for 1D-position sensitive X-ray spectroscopy; the multi-anode silicon drift detector (SDD). The developed prototype is an ideal candidate for X-ray diffraction applications. Moreover, due to a high flexibility of its design, SDDs can be utilized in many other applications where sensing of X-rays in the range from 200 eV to 20 keV with an ultimate energy resolution is needed, e.g. X-ray fluorescence spectroscopy, X-ray holography and synchrotron experiments.
