Radiation effects of CERN-PS 24 GeV/c protons in silicon strip sensors, evaluated with ATLAS18 ITk strip sensor test structuresMandić, Igor (Avtor) Mikuž, Marko (Avtor) hadron collideratlas experimentsilicon strip sensorssilicon strip detectorscharge collectionradiation hardnessTest structures from the ATLAS18 ITk strip detector wafers were irradiated with 24 GeV/c protons. These test structures were positioned at various angles with respect to the proton beam. Blocks of G10 material were placed in front of these test structures to study the effect of scattering of primary protons on the received particle fluence. The results confirm that both the incidence angle of the beam and scattering significantly influence the actual fluence to which the samples are exposed. Miniature strip detectors, first irradiated with protons, were also irradiated with reactor neutrons, to a combined fluence of ɸ$_{neq}$ = 1.6 × 10$^{15}$ cm$^{−2}$. The combination of proton and neutron fluences matched the combination expected in the most exposed part of the strip detector in the ALTAS Inner Tracker (ITk). Good charge collection was measured confirming that the strip detectors are sufficiently radiation hard for successful operation to highest fluences expected at the HL-LHC.20262026-05-19 15:02:53Članek v reviji182623UDK: 539.1ISSN pri članku: 1872-9576DOI: 10.1016/j.nima.2025.170917COBISS_ID: 247669251sl
