Sensor response and radiation damage effects for 3D pixels in the ATLAS IBL Detector

Popis výsledku v původním jazyce

Pixel sensors in 3D technology equip the outer ends of thestaves of the Insertable B Layer (IBL), the innermost layer of theATLAS Pixel Detector, which was installed before the start of LHCRun 2 in 2015. 3D pixel sensors are expected to exhibit moretolerance to radiation damage and are the technology of choice forthe innermost layer in the ATLAS tracker upgrade for the HL-LHCprogramme. While the LHC has delivered an integrated luminosity of ≃ 235 fb−1−1 since the start of Run 2, the 3D sensorshave received a non-ionising energy deposition corresponding to afluence of ≃ 8.5 × 101414 1 MeVneutron-equivalent cm−2−2 averaged over the sensor area. Thispaper presents results of measurements of the 3D pixel sensors'response during Run 2 and the first two years of Run 3, withpredictions of its evolution until the end of Run 3 in 2025. Dataare compared with radiation damage simulations, based on detailedmaps of the electric field in the Si substrate, at various fluencelevels and bias voltage values. These results illustrate thepotential of 3D technology for pixel applications in high-radiationenvironments.
