The signal charge spectrum evolution for the scCVD diamond sample irradiated with 200 MeV pions biased at $E = +2 \mathrm{V}/\mathsf{\mu }\mathrm{m}$. The pulse height spectrum before irradiation was measured using a setup with a ⁹⁰Sr $\beta$-source and a single pad metallization on the diamond, biased at 1 V/$\mathsf{\mu }\mathrm{m}$, since the detector collects all the charge at a bias voltage of 200 V. The integral of each spectrum was normalized to unity.
