8 : /// \brief EMCal geometry, singleton
9 : ///
10 : /// Geometry class for EMCAL : singleton
11 : /// EMCAL consists of layers of scintillator and lead
12 : /// with scintillator fiber arranged as "shish-kebab" skewers
13 : /// Places the the Barrel Geometry of The EMCAL at Midrapidity
14 : /// between 80 and 180(or 190) degrees of Phi and
15 : /// -0.7 to 0.7 in eta
16 : ///
17 : /// EMCAL geometry tree:
18 : /// EMCAL -> superModule -> module -> tower(cell)
19 : /// Indexes
20 : /// absId -> nSupMod -> nModule -> (nIphi,nIeta)
21 : ///
22 : /// Name choices:
23 : /// EMCAL_PDC06 (geometry used for PDC06 simulations, kept for backward compatibility)
24 : /// = equivalent to SHISH_77_TRD1_2X2_FINAL_110DEG in old notation
25 : /// EMCAL_COMPLETE (geometry for expected complete detector)
26 : /// = equivalent to SHISH_77_TRD1_2X2_FINAL_110DEG scTh=0.176 pbTh=0.144
27 : /// in old notation
28 : ///
29 : /// EMCAL_FIRSTYEAR - geometry for December 2009 to December 2010 run period
30 : /// with four Super Modules
31 : ///
32 : /// Adding V1 (EMCAL_FIRSTYEARV1, EMCAL_COMPLETEV1) - geometry from December 2009 ;
33 : /// 1. Fixed bug for positions of modules inside SM
34 : /// (first module has tilt 0.75 degree);
35 : /// 2. Added Al front plate (width 1 cm) and 2 paper sheets per sampling
36 : /// layer (additional 0.2 mm)
37 : /// The sizes have updated with last information from production
38 : /// drawing (end of October 2010).
39 : /// 3. COMPLETEV1 contains now only 10 SM for runs for year 2011
40 : /// 4. COMPLETE12SMV1 contains 12 SM for runs from year 2012 and on
41 : /// 5. COMPLETE12SMV1_DCAL contains 12 SM and 6 DCal SM
42 : /// 6. COMPLETE12SMV1_DCAL_DEV contains 12 SM and 10 DCal SM
43 : /// 7. COMPLETE12SMV1_DCAL_8SM contains 12 SM and 6 DCal SM and 2 extentions
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 : ///
