  • 中图分类号: TL503.5;TL503.6

  • 摘要: 文章描述了中国科学院近代物理研究所(IMP)正在研制的IMP质子治癌装置3D剂量测量系统。该系统主要由2D剖面探测器、辐照深度和剂量探测器、射程调整器等组成。其中,多级双维位置灵敏平行板雪崩探测器(MPPAC)使用C3F8作为工作气体,工作气压为700Pa,阳极电压为+700V。对3组分α粒子测得位置分辨为0.54mm(FWHM)。

     

    Abstract: A 3D dosimetry system of proton therapy facility was designed and constructed in Institute of Modern Physics. It is composed of 2D profile detector, depth-dose detector and rang tuning detector. Under the 2D detector operating gas C_(3)F_(8) with the pressure of 700 Pa and the anode voltage of +700 V, the position resolution of about (0.54) mm(FWHM) is achieved for 3-components α particles.
