摘要

起始计数器是一个闪烁体探测器,设计用于测量稀有同位素加速器综合体在线实验(RAON)大型接收多用途光谱仪(LAMPS)实验的入射光束的参考时间。探测器由一个平面塑料闪烁体和连接在闪烁体两边的多像素光子计数器(MPPC)阵列组成。为了了解起始计数器的性能,我们使用 GENAT4 工具包开发了一个模拟框架,它可以模拟光学光子的产生和传播。闪烁器和MPPC的详细光学特性是在模拟5.48 MeV \(α)光束(对应于\(^{241}\)Am辐射源)时实现的。在本文中,我们将报告模拟框架的开发及其性能,包括其在作为典型稀有同位素束的 250 MeV/A (^{132}\)Sn 束中的应用。

GEANT4 simulation study of the start counter for the LAMPS experiment at RAON

GEANT4 simulation study of the start counter for the LAMPS experiment at RAON

GEANT4 simulation study of the start counter for the LAMPS experiment at RAON

The start counter is a scintillator detector designed to measure the reference time of the incident beam for the Large Acceptance Multi-Purpose Spectrometer (LAMPS) experiment at the Rare isotope Accelerator complex for ON-line experiments (RAON). The detector is composed of a plane of plastic scintillator and Multi-Pixel Photon Counter (MPPC) arrays attached to both edges of the scintillator. To understand the performance of the start counter, a simulation framework has been developed using the GENAT4 toolkit, which can simulate the generation and propagation of optical photons. Detailed optical properties of the scintillator and MPPCs are implemented in the simulation for a 5.48 MeV \(\alpha\) beam corresponding to a \(^{241}\)Am radiation source. In this paper, we will report on the development of the simulation framework and its performance, including its application to the 250 MeV/A \(^{132}\)Sn beam as a typical rare isotope beam.
