Pixel sensors with slim edges and small pitches for the CMS upgrades for HL-LHC

摘要

Planar n-in-n silicon detectors with small pitches and slim edges are being investigated for the innermost layers of tracking devices for the foreseen upgrades of the LHC experiments. Sensor prototypes compatible with the CMS readout, fabricated by Sintef, were tested in the laboratory and with a 120 GeV/c proton beam at the Fermilab test beam facility before and after irradiation with up to 2 × 10~(15) n_(eq)/cm~2 fluence. Preliminary results of the data analysis are presented.
