- W2791316663 abstract "Over the last decades, improvements in microelectronics technology havefostered signicant progress in all fields of engineering, science and also inradiation detection. The main challenge in designing radiation detectors isto develop systems based on front-end electronics that is able to cope withhigh radioactive environment, satisfy very high resolution requirements andcomply with high particle rates. This thesis work focuses on the analysis anddevelopment of novel and intelligent solutions for electronics system, especiallysuited for radiation detectors. In particular, two different applications areconsidered here.The first one concerns the design of a portable and affordable detectorsystem for continuous indoor Radon detection, based on SiPM technology. Asimple analog front-end with optimized low-noise performances and reducedpower consumption has been designed for counting each alpha particle thatoccurs in the detector after Radon decay. The readout electronics is integratedwith a suite of environmental sensors on a full-custom Printed Circuit Board.Compared to all the commercial Radon detector nowadays available, the developed system is able to detect reliable value of indoor Radon concentrationwithin few hours. The system also exploits the recent capabilities of microelectronic devices by including advanced functions such as Bluetooth datatransmission and energy harvesting.In high-energy physics experiments, with particular emphasis on the HL-LHC environment, pixel detectors have to satisfy aggressive requirementsconcerning high granularity, high rate capability and low power consumption.With the advent of accessible modern technology such as 65 nm CMOS, theprocessing speed and reduced power consumption can be achieved. In orderto meet such specications, a new pixel mixed signal ASIC has been designedas a prototype front-end for the HL-HLC pixel readout system, within theframework of RD53 collaboration. The ASIC front-end includes signal processing and synchronous analog-to-digital conversion within one Bunch Crossingperiod. Thus, the emphasis of the work is on the feasibility of a synchronousADC within the HL-LHC environment, able to ensure high performances interms of low noise, power dissipation and high speed. Finally, a novel andintelligent digital architecture has been proposed, in order to focus the eortsof the front-end on the implementations of three main features: a novel datasparsication method, a clusterization scheme at the hardware level itself andfast Region-Of-Interest (ROI) trigger capability." @default.
