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.
