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 | |
3d841a9f | 37 | // |
38 | // EMCAL_FIRSTYEAR - geometry for December 2009 to December 2010 run period | |
39 | // with four Super Modules | |
40 | // | |
171d2441 | 41 | // Adding V1 (EMCAL_FIRSTYEARV1, EMCAL_COMPLETEV1) - geometry from December 2009 ; |
3d841a9f | 42 | // 1. Fixed bug for positions of modules inside SM |
43 | // (first module has tilt 0.75 degree); | |
44 | // 2. Added Al front plate (width 1 cm) and 2 paper sheets per sampling | |
45 | // layer (additional 0.2 mm) | |
46 | // The sizes have updated with last information from production | |
47 | // drawing (end of October 2010). | |
171d2441 | 48 | // 3. COMPLETEV1 contains now only 10 SM for runs from 2011 |
3d841a9f | 49 | // |
0c5b726e | 50 | // EMCAL_WSUC (Wayne State test stand) |
51 | // = no definite equivalent in old notation, was only used by | |
52 | // Aleksei, but kept for testing purposes | |
