LED Diffuser Ball in Water Pool LEDs are placed in the positions specified in the Near Pool and Far Pool Diagram (inside the red squire) above for this simulation We simulate 2000 events with only one LED flashing at a time

How to generate LED Diffuser Ball MC import GenTools from GenTools.Helpers import DiffuserBall ball = DiffuserBall() ball.setVolume(myVolume) ball.setPosition( [xpos*units.cm, ypos*units.cm, zpos*units.cm] ) ball.ball.PhotonsPerEvent = intensity gtc = GenTools.Configure() # GEANT4 import DetSim detsim = DetSim.Configure(physlist = DetSim.physics_list_basic) # Next do the electronic simulation and trigger simulation # At the end you will get a ROOT file with EVENT and RUNHEAD info
