Figure 4
Energy response of the LGAD microstrip sensors at different energies. (a) Pulse height distributions acquired using the Gotthard-1.7 chip at 120 V bias voltage. The markers represent the experimental data, while the solid lines are the resulting fit with a convolution of an exponential function and a Gaussian curve. (b) S-curves, i.e. the integrated spectra, acquired using Mythen-II at 150 V bias voltage. The markers represent the experimental data, while the solid lines are the resulting fit with the S-curve model described by Bergamaschi et al. (2010). (c) Energy calibration using Gotthard-1.7. (d) Energy calibration using Mythen-II. |
