Pixel size analysis of EIC-dRICH SiPMs was studied by obtaining photon hit positions from digitized(includes pixel size uncertainity) and undigitized hits(actual coordinates, independent of pixel size). The following files were generated for digitized hits:
Analysis done by Nebin George
Total files:581 hepmc files & 577 analysis files
The HEPMC filenames have the format PID_MOMENTUM_ETABIN_PHIBIN.hepmc. Each file has 200 events.
The Analysis filenames have the format PID_MOMENTUM_ETABIN_PHI.root. Each file has 200 events.
The HEPMC and Analysis files are generated for the following PID, MOMENTUM, ETA and PHI values.
Momentum values are: [5,15,25,35,45,55] in Gev/C.In the code, internally momentum is smeared between +/- 0.1 GeV/C.
PID's are: [211(Pion),321(Kaon),2212(Proton)]
ETABIN : [5, 10, 15, 20], corresponding ETA VALUE: [2, 2.5, 3, 3.5].
| Eta Bin | Range |
|---|---|
| 5 | {1.999, 2.001} |
| 10 | {2.499, 2.501} |
| 15 | {2.999, 3.001} |
| 20 | {3.499, 3.501} |
PHI BIN : [0,1,2,3,4,5,6,7], corresponding PHI VALUE: [0, 45, 90, 135, 180, 225, 270, 315] in degrees.
| Phi Bin | Phi Value(degrees) |
|---|---|
| 0 | 0 |
| 1 | 45 |
| 2 | 90 |
| 3 | 135 |
| 4 | 180 |
| 5 | 225 |
| 6 | 270 |
| 7 | 315 |
