| A schematic cross-section of a SDHCAL active layer (not to scale). |
| (a): Length of steps in~mm as a function of $\Delta_z$ in~mm. This figure is zoomed on the short steps region to show that most of the short steps are located at the detector's boundaries ($|\Delta_z|\simeq$ 0.6~mm). (b): Measured SDHCAL layer ASIC efficiency map example. Each bin corresponds to the mean efficiency measured in one ASIC which corresponds to $8\times8$ readout pads. |
