Technological solutions for the transfer to large area microstrip radiation silicon sensors are presented for the upgrade of the ATLAS detector. A new Automatic Layout Generation Tool has been developed to easily adapt the design of the sensors, investigating also the fabrication processes involved in 6-inch wafer technology. Inter-strip and radiation hardness characterization of prototype sensors...
A further development of a new technological solution to improve the beam-loss protection of silicon strip sensors used in large High Energy Physics experiments is presented. Previous studies show that the high strip resistance limits the beneficial effect of full Punch-Through protection (PTP) structures to the area near the structures. In our approach, we extended the PTP protection to the full...
A new technological solution to improve the beam-loss protection of silicon strip sensors used in large High Energy Physics experiments is presented. In the current ATLAS-SCT, sensors have Punch-Through protection (PTP) structures included to develop low impedance from the strip to the bias ring in case large voltages exceed some threshold that could damage the strip coupling capacitance. Previous...
The ALIBAVA is a compact and portable system for characterization of silicon microstrip radiation detectors. Actually, the ALIBAVA system is conceived to easily characterize multichannel semiconductor detectors, providing high sensitivity to low signals and high speed. The front-end electronics is based on a low noise ASIC with 128 input channels. Beyond its scientific and sensor R&D applications,...
In this work, results of simulation of irradiated edgeless detectors for close to beam experiments are presented. The charge collection efficiency at the sensitive cut for minimal ionizing particles was numerically simulated in the frame of amorphous silicon model of heavily damaged cut surface. It is shown that the charge collection reduction for non- irradiated detectors is expected in the region...
