摘　　要：采用碘化铅(PbI_2)晶体材料,设计了碘化铅X射线探测器及放大采样电路。在采用熔体法合成碘化铅多晶原料的基础上,用垂直布里奇曼法生长碘化铅晶体和TO8金属管壳(CETC 44,0.01 mm铝箔窗口)封装,对电荷放大和采样电路进行设计。实验结果表明,碘化铅制作成的探测器X射线辐射下,线性响应好,可用于室温核辐射检测仪的研究。In this paper, the innovative lead iodide （PbI2 ） crystal materials are adopted in the design of the iodide lead room temperature X - ray detector and the amplification sampling circuit. The polycrystalline lead is synthesized by the melt method, with the vertical Bridgman method for lead iodide crystal growth and TO8 metal shell （CETC 44 mm aluminum foil, 0.01 window） encapsulation. The design of the electric charge amplifier and sampling circuit is presented. The experimental results show that the lead iodide detector achieves good linear response under X - ray radiation, and can be used for room temperature nuclear radiation detector research.
