Question Number of initial events and Statistic 

Forum: Event and Track Management
Date: 17 Sep, 2013
From: Kim Tuyet <Kim Tuyet>

Hello all. My name is Kim Tuyet Tran. I am currently a technician of a Nuclear Techniques Laboratory, University of Science - Ho Chi Minh city, Viet Nam.

In a research of Compton Scattering, because of the big geometry of lead collimator, the detected event is very low.
Initial events is 2E+09 but detected events is 3E+02. Thus, this detected events number is not good for statistic.
I have two solutions and I hope you can review and give me some advices:
 1. The initial events in Geant4 is limited by 2E+09.
    I run 4E+09 but the initial events stop at 2.2E+09.
    Is this any possible way to increase the initial events?
 2. The second solution is run the input file many times (maybe 3 or 4 times) and then combine (integrate) the result files.

I hope I do not waste your time
Expecting your help.
