a3dfe79c | 9 | // Geometry class for PHOS : singleton |
10 | // PHOS consists of the electromagnetic calorimeter (EMCA) | |
11 | // and a charged particle veto either in the Subatech's version (PPSD) | |
12 | // or in the IHEP's one (CPV). | |
13 | // The EMCA/PPSD/CPV modules are parametrized so that any configuration | |
14 | // can be easily implemented | |
15 | // The title is used to identify the version of CPV used. | |
