19 | // Geometry class for EMCAL : singleton | |
20 | // EMCAL consists of layers of scintillator and lead | |
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_FIRSTYEARV1 - geometry for December 2009 to December 2010 run period; | |
38 | // fixed bug for positions of modules inside SM | |
39 | // (first module has tilt 0.75 degree); | |
40 | // the sizes updated with last information from production | |
41 | // drawing (end of October 2010). | |
42 | // | |
43 | // EMCAL_COMPLETEV1: Same fixes as FIRSTYEAR and 10 SM instead of 10+2 half SM | |
44 | // | |
45 | // EMCAL_WSUC (Wayne State test stand) | |
46 | // = no definite equivalent in old notation, was only used by | |
47 | // Aleksei, but kept for testing purposes | |
48 | // | |
49 | // etc. | |
