Annotation: Röntgenová rádiografia sa stala súčasťou mnohých oblastí nedeštruktívnej diagnostiky a testovania. Digitalizácia v tejto oblasti viedla k vývoju tzv. radiačných kamier používaných pre digitálnu rádiografiu a tomografiu. Kamera typu TIMEPIX patrí k zariadeniam najnovšej generácie pracujúcich v tzv. „single photon counting“ móde. Vrámci riešenia dizertačnej práce bude študent vyvíjať nové typy senzorov pre uvedenú kameru, a to na báze perspektívnych polovodičových materiálov ako sú GaAs a SiC, ktoré sa vyznačujú vysokou radiačnou odolnosťou, rýchlou odozvou a vyššou detekčnou účinnosťou v porovnaní so súčasnými najmodernejšími senzormi na báze kremíka.
Annotation in English: X-ray radiography became a part of many areas of non-destructive diagnostic and testing. Its digitalization led to development of so called radiation cameras for digital radiography and tomography. The camera of a TIMEPIX type belongs among the newest generation of digital imaging devices operating in single photon counting mode. The student will develop new types of sensors for this kind of camera, based on the most perspective semiconductor materials available, like GaAs and SiC, exhibiting higher radiation hardness, fast response and higher detection efficiency in comparison with recent silicon sensors.
