摘要:

一个像素化的硅探测器,最初开发的粒子物理实验,用于在水幻影的Co-60辐照器的光束轮廓测量。将射束轮廓与用精确电离室测量的轮廓进行比较。像素探测器和精确定位腔室相对轮廓的差异在约0.02以内,并且在使用像素探测器的蒙特卡罗模拟计算校正因子后,差异减小到几乎小于0.005。探测器的测量脉冲高度的能力被用来记录在水中的Co-60束的电子脉冲高度谱,结果与模拟吻合得很好。

英文摘要:

A pixelated silicon detector, developed originally for particle physics experiments, was used for a beam profile measurement of a Co-60 irradiator in a water phantom. The beam profile was compared to a profile measured with a pinpoint ionization chamber. The differences in the pixel detector and pinpoint chamber relative profiles were within approximately 0.02, and after calculating correction factors with Monte Carlo simulations for the pixel detector, the differences were decreased to almost less than 0.005. The detector's capability to measure pulse-height was used to record an electron pulse-height spectrum in water in the Co-60 beam, and the results agreed well with simulations.
