Mass spectrum of the MTOF sensor showing the contributions of the isotopes ﹩^{14,\, 15}﹩N﹩^{+}﹩, ﹩^{16}﹩O﹩^{+}﹩, and ﹩^{28,\, 29,\, 30}﹩Si﹩^{2+}﹩. The line shape of the ﹩^{14}﹩N﹩^{+}﹩ and ﹩^{28}﹩Si﹩^{2+}﹩ peak is adapted to the line shape of the ﹩^{16}﹩O﹩^{+}﹩ peak. The fit methods M1 and M2 are represented by the solid line in the full channel range and the dashed line in channels 453–470, respectively. With "e.r.," we mark the well‐understood instrumental effect of electronic ringing caused by reflections of the electronic start signal. The arrow points to the signature of the analog‐to‐digital conversion (ADC) effect. This effect is observed in any channel where ﹩t_{\mathrm{ADC}\,}=\sum_{i=n_{0}}^{9}a_{i}2^{i}﹩, with ﹩a_{i}=0﹩, 1 (the larger ﹩n_{0}﹩, the larger the ADC effect). For channels t slightly higher than t_ADC, the TOF signal is lower; for t slightly lower than t_ADC, the signal is higher. However, the count number that is totaled over the neighboring channels of t_ADC remains strictly conserved.
