我们描述了一个质子射程照相系统，它的成像面积为10×10厘米(2)，部署了一对气体电子倍增器位置敏感探测器和一个闪烁体堆栈来测量穿过靶后的剩余质子射程。该探测器已经在实验室和保罗·谢勒研究所的光束曝光中进行了测试；用几个厚度和成分不同的模体记录的图像证实了该仪器的亚毫米精度和极少的能量分辨率。一种设计相同、接受度更高的新设备--30x30厘米(2)--正在建设中。(C)2010爱思唯尔B.V.保留所有权利。
We describe a Proton Range Radiography system with an imaging area of 10 x 10 cm(2), deploying a pair of Gas Electron Multiplier position-sensitive detectors and a scintillator stack to measure the residual proton range after crossing a target. The detector has been tested in the laboratory and in beam exposures at the Paul Scherrer Institute; images recorded with several phantoms of variable thickness and composition confirm the sub-millimetre accuracy and few percent energy resolution of the instrument. A new device with identical design and larger acceptance, 30 x 30 cm(2), is in construction. (C) 2010 Elsevier B.V. All rights reserved.
