AC- and DC-coupled n-type strips with three different pitches (wide, default and narrow) were processed on high-resistivity p-type FZ silicon substrates by Hamamatsu Photonics. The miniature sensors were irradiated with 70-MeV protons at CYRIC, Tohoku University (Japan) and reactor neutrons at the Jožef Stefan Institute (Slovenia) to three different 1-MeV neutron equivalent fluences: 0.5, 1 and 2 x 10 15 neq cm −2 . The upper fluence range exceeds the highest anticipated in the innermost part of the ATLAS ITk-Strips over the HL-LHC lifetime ( ∼ 1.25 × 10 15 n eq cm 2 ). The charge collection in the test sensors was evaluated systematically using a 90 Sr β -source and an Alibava analogue readout system at reverse-bias voltages up to 1000 V.
