Development of silicon micro strip detector for proton computed tomography

本研究的目的是开发一种小型的质子计算机断层扫描检测设备。利用硅微带探测器（SSD）获得质子径迹。两组X和y条探测器分别放置在物体的后面和前面。用NaI（Tl）探测器测量了剩余质子能。我们测量了NaI（Tl）探测器的能量分辨率和简单形状物体的二维图像。研究发现，独立测量上游轨迹和下游轨迹对目标的空间分辨率非常有用。

The purpose of this study is to develop a small detection apparatus for proton computed tomography. Silicon micro strip detectors (SSD) were used to obtain the proton track. Two sets of the X- and Y-strip detectors were each placed behind and ahead of the object. The residual proton energy was measured by the NaI(Tl) detector. We have measured the energy resolution of the NaI(Tl) detector and the 2D images of simple-shaped objects. It is found that the measurement of the upstream trajectory and the downstream independently is quite useful for spatial resolution of the object.
