Detailed Description

Author: Jan Balewski, Wei-Ming Zang

FGT slow simu code allows processing of Geant hits from simulation thrugh semi-realistic FGT detector response package and addition of real pedestals for the subset of fired strips.

Most of parameters are obtined from the dedicated DB table: "Calibrations/fgt/fgtSimuParams"

Those are the valuse loaded to DB:

table.param[0] =102;// fgt-simu-setup version #

analog signal propagation table.param[1] = 9992; // meLossTab[9993-10000]=5.0E+03 to 6.0E+06 (too high) are cut off. They are replaced by meLossTab[9992]=4.78E+03 in simulation. table.param[2] = 40. ; //( ions/cm) # of primary pairs produced per cm of path table.param[3] = 80.e-9; // (seconds) track ignored by FGT slow sim table.param[4] = 0.035 ; // cm, for 2D gauss smearing, default=0.035 for FNAL table.param[5] = 0.005; // (GeV) track ignored by FGT slow sim table.param[6] = 0.017; // (cm per 1 cm of path) table.param[7] = 6; // # of bins in 2D distribution to store 2D gauss

digitalization table.param[10] = 5.0; // drop strips below it table.param[11] = 1000; // in a.u. used in simu table.param[12] = 2.0; // a factor making simulated ADCs comparable to 2012 pp510 data table.param[13] = 0.45; // divide charge between P/R plane

They are mapped to real variables in the InitRun()

If DB fails to deliver reasonable params fgt-slows-simu flips to the locked state, par_badSetup!=0, and ignores FGT data for the whole job.

Steps of data processing:

-#  unpack_g2t_hits() : converts hardcoded geant volumes to FGT official indexing, filters every track segment passimg thrugh the sensitve GEM volume.
 The accepted track segements are stored in 6x4=24 independent, internal lists: mG2tHitList[iDisc][iQuad].push_back(aux)

-# The analog part of the 'slow simulation' is performed independently for each quadrant, using track segemnt lists as input. The working horse is

responseMipModel( len, dir) - taking as input only lenght and direction of each track segment.

   WARN: this code treats all partiles as MIPs or drops them 
   if they  have too low. It is not bad for high pT leptons from W, but for 
   soft tracks in a jet it generates too few ion pairs and simulated 
   amplitude may be many times too small. 
   This should be improved in the next wave of FGT slow simu tinning.
   September 2011, Jan B.

responseMipModel( generates realistic distribution of primary ionization pairs along the track path, using meLossTab[]. The details are described in Frank's thesis: http://drupal.star.bnl.gov/STAR/system/files/2001-F.Simon-diploma.pdf chapter 3. "The GEM Concept" .

Individual pairs are amplified according to the distance to the 1st GEM foil and their location is displaced transversely using Gauss distribution. This model does not simulate 7 time bins *** Finally, the addHit() stores the total charge of given pair as 2D gaussion in the target high resolution histogram quadDigitizationXY, covering area of the whole quadrant with 2D bins 0.2mmx0.2mm. This finishes the analog part of fgt-slow-simu.

Digitalizaton process, executed by projectQuad2strips(), projects of 2D charge in to two 1D plaines of strips. The external methods: Int_t iRadID=StFgtGeom::rad2LocalStripId(r,phi,&binFrac); Int_t iPhiID=StFgtGeom::phi2LocalStripId(r,phi,&binFrac); provide mapping from 2D plane location to strip ID. The charge accumlated in all bins of 2D histo (above some threshold) are project in to two planes. R & Phi planes consist of strips overlaping 100%, charge sharing is set by single DB param *** It is known the spacer grid implement in GEANT results with less charge absorbtion than for FGT as build. ***
Storing of fired strips in to StFgtStrip-collection is done by exportStripPlane2StEvent(). There is a threshold below which strips are ignoted. To help find clusters up to 3 strips after each fired strips are stored.

The switch_addPeds allows adding pedestals to the select strips. If activated, it checks for bad pedestal and drops such strips.
