Abstract Active silicon detectors built on p-type substrate are a promising technological solution for large area silicon trackers such as those at the High Luminosity LHC, but the radiation hardness of this novel approach has to be evaluated. Active n-in-p strip detector prototypes CHESS2 for ATLAS with different substrate resistivities in the range of 20–1000 Ωcm were irradiated with neutrons and protons up to a fluence of 2×10$^{15} $n$_{eq}$ cm$^{-2}$ and 3.6×10$^{15} $n$_{eq}$ cm$^{-2}$ . Charge collection in passive test structures on the chip was evaluated using Edge-TCT and minimum ionising electrons from $^{90}$Sr. Results were used to assess radiation hardness of the detector in the given fluence range and to determine parameters of initial acceptor removal in different substrates.
