| 21 | // with scintillator fiber arranged as "shish-kebab" skewers |
| 22 | // Places the the Barrel Geometry of The EMCAL at Midrapidity |
| 23 | // between 80 and 180(or 190) degrees of Phi and |
| 24 | // -0.7 to 0.7 in eta |
| 25 | // |
| 26 | // EMCAL geometry tree: |
| 27 | // EMCAL -> superModule -> module -> tower(cell) |
| 28 | // Indexes |
| 29 | // absId -> nSupMod -> nModule -> (nIphi,nIeta) |
| 30 | // |
| 31 | // Name choices: |
| 32 | // EMCAL_PDC06 (geometry used for PDC06 simulations, kept for backward compatibility) |
| 33 | // = equivalent to SHISH_77_TRD1_2X2_FINAL_110DEG in old notation |
| 34 | // EMCAL_COMPLETE (geometry for expected complete detector) |
| 35 | // = equivalent to SHISH_77_TRD1_2X2_FINAL_110DEG scTh=0.176 pbTh=0.144 |
| 36 | // in old notation |
| 37 | // EMCAL_WSUC (Wayne State test stand) |
| 38 | // = no definite equivalent in old notation, was only used by |
| 39 | // Aleksei, but kept for testing purposes |
