Description |
Plastic scintillator based detectors are commonly used in cosmic ray, high energy and nuclear physics experiments for study of charged radiation due to their fast response time (~1 ns), rugged nature and reasonable cost. The advent of wave-length shifting fibers has provided numerous options to explore newer designs and improved performance for these detectors. However, design of a new detector starting with a prototype is an expensive and time consuming option. On the other hand, if realistic Monte Carlo simulations could be performed to evaluate the performance of scintillator detector, then that could result in considerable savings in effort, time and cost. The G3sim is a realistic Monte Carlo code, developed entirely in-house, to aid the design of new scintillator detectors for the expansion of the GRAPES-3 air shower array at Ooty. It has successfully reproduced the measurements of photon yield, surface uniformity and the response time for different scintillator designs. G3sim is compact (~1000 lines of C++ code) with a simple input format, making it easy to understand and use. We have made it available to the scientific community on request. In this talk, I will discuss various features of G3sim and its validation for the GRAPES-3 scintillator detector followed by a small demonstration on its usage. |
