lars
11d01d7015
Mirrors run_pbwo4 but alternates thin absorber and active layers, with four selectable configs (by name or 1-based index): pb_scint, fe_scint, w_scint_ecal (homogeneous ECAL-like preshower + W/scint sampling section), and pb_lar. Each is sized to reach ~20-25 X0 of absorber despite the dilution from inactive gaps. Wired into the top-level CMakeLists, superbuild, and Dockerfile alongside run_pbwo4.
