Detailed Description

class TileDetDescriptor

This class contains the detector description information for the Tile calorimeters: Barrel, Ext.Barrel, Gap detector.

There are 3 detectors (bar,ext.bar,gap) * 2 sides = 6 regions in TileCal Granularity in phi is one and the same for all cells in the region and all phi variables are scalars (min_phi, max_phi, dphi, nphi) Granularity in eta can be different for different samplings or towers and all eta variables are arrays (min_eta, max_eta, deta, neta) TileCal has 3 samplings and index in "eta" arrays corresponds to sampling number: eta[0] - samling A, eta[1] - sampling BC, eta[2] - sampling D In Gap detector (detector=3) apart from normal samplings there are 4 so-called gap scintillators. For all these scintillators sampling=3 and tower number is used instead of sampling number to distinguish them. In current geometry gap scintillators are positioned in towers 10,11,13,15 hence information about them is saved in eta[10], eta[11], eta[13], eta[15] variable "n_samp" is the length of "eta" arrays, n_samp=3 for barrel and ext. barrel and n_samp=16 for gap detector. Rcenter[] is the radius of the center of cells in the given sampling It can be used to re-calculate shift in eta due to zshift etashift = zshift * tanh(eta) * tan(2 * atan(exp(-eta))) / Rcenter dr[] is the thickness of the samplings in R
