e8c0d6bb 19// Geometry class for EMCAL : singleton
b13bbe81 20// EMCAL consists of layers of scintillator and lead
d297ef6e 21// with scintillator fiber arranged as "shish-kebab" skewers
ffa6d63b 22// Places the the Barrel Geometry of The EMCAL at Midrapidity
d87bd045 23// between 80 and 180(or 190) degrees of Phi and
ffa6d63b 24// -0.7 to 0.7 in eta
d297ef6e 25//
1d46d1f6 26// EMCAL geometry tree:
2bb3725c 27// EMCAL -> superModule -> module -> tower(cell)
1d46d1f6 28// Indexes
2bb3725c 29// absId -> nSupMod -> nModule -> (nIphi,nIeta)
1d46d1f6 30//
d297ef6e 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
171d2441 37// EMCAL_FIRSTYEARV1 - geometry for December 2009 to December 2010 run period;
3d841a9f 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).
171d2441 42//
a520bcd0 43// EMCAL_COMPLETEV1: Same fixes as FIRSTYEAR and 10 SM instead of 10 + 2 one_third SM, for 2011 runs
d7f5c01a 44//
45// EMCAL_COMPLETE12SMV1: contains 12 SM for runs from year 2012 and on
3d841a9f 46//
d297ef6e 47// EMCAL_WSUC (Wayne State test stand)
48// = no definite equivalent in old notation, was only used by
49// Aleksei, but kept for testing purposes
50//
51// etc.
e8c0d6bb 52
d297ef6e 53//
e8c0d6bb 54// Usage:
55// You can create the AliEMCALGeometry object independently from anything.
56// You have to use just the correct name of geometry. If name is empty string the
57// default name of geometry will be used.
