The STAR experiment

 

 

 

 

I am following Rosi's excellent instructions, with modifications for four crates.

The MIP peak position depends on the Vbias, and we attempt to put all the MIP peaks at roughly the same ADC value, by adjusting voltages through a bias scan.

Description

 Pythia 8 simulation for single diffractive process

 pp 200 GeV 

 Simulation process soft QCD: single diffractive 

  only keep *.starsim.root files

  1k event each file, totally 1k files, please do not merge the files. We need to do detector level simulation.
