我们已经构建了一个基于GEANT 4的详细的软件模型的塑料闪烁体块中的光子输运,并使用它来研究NEMO-3和SuperNEMO量热计在实验中,旨在寻找无中微子双β衰变。我们比较我们的模拟测量使用转换电子从校准源of 207 Bi,并表明,协议得到改善,如果考虑到波长依赖的性能的量热计。在这篇文章中,我们简要介绍了我们的建模方法和我们的研究结果。
We have constructed a GEANT4-based detailed software model of photon transport in plastic scintillator blocks and have used it to study the NEMO-3 and SuperNEMO calorimeters employed in experiments designed to search for neutrinoless double beta decay. We compare our simulations to measurements using conversion electrons from a calibration source of207Bi and show that the agreement is improved if wavelength-dependent properties of the calorimeter are taken into account. In this article, we briefly describe our modeling approach and results of our studies.
