塑料发泡剂的温度依赖性

Temperature dependence of plastic scintillators

Luis Peralta

摘要:

塑料闪烁体探测器已被用作剂量计进行研究,因为它们提供了传统电离室的具有成本效益的替代方案。另一方面,一些文章报道了不期望的响应依赖于束能量和温度,这增强了确定适当的校正因子的必要性。在这项工作中,我们研究了四种塑料发光体(BCF-10,BCF-60,BC-404和RP-200 A)和两种透明光纤(BCF-98和SK-80)的光产额温度依赖性。使用50 kVp X射线束进行测量,以产生闪烁和/或放射性发光信号。对每个闪烁体扫描0至40度范围,并获得温度系数。

英文摘要:

Plastic scintillator detectors have been studied as dosimeters, since they provide a cost-effective alternative to conventional ionization chambers. On the other hand, several articles have reported undesired response dependencies on beam energy and temperature, which enhances the necessity to determine appropriate correction factors. In this work, we studied the light yield temperature dependency of four plastic scintillators (BCF-10, BCF-60, BC-404 and RP-200A) and two clear fibers (BCF-98 and SK-80). Measurements were made using a 50 kVp X-ray beam to produce the scintillation and/or radioluminescence signal. The 0 to 40 degrees celsius range was scanned for each scintillator, and temperature coefficients obtained.
