Designs of hodoscopes of nuclear fragments based on quartz and scintillation plates with light pickup by silicon avalanche photodiodes are described. Hodoscopes are planned for use in the BM@N experiment for registration of heavy nuclear fragments near the axis of the heavy ion beam. The results of measurements of light yields in detector elements based on quartz and scintillation plates on the electron beam of the synchrotron "Pakhra" (LPI) are presented. The measured nonuniformity of the light collection shows that readout from both sides of hodoscope detector elements is needed.

BM @ N实验用前视镜原型的振幅参数

描述了基于石英和闪烁板的核碎片全息图的设计，并利用硅雪崩光电二极管进行了光拾取。计划在BM @ N实验中使用镜筒，以记录重离子束轴附近的重核碎片。给出了在同步加速器“ Pakhra”（LPI）的电子束上基于石英和闪烁板的探测器元件中光产率的测量结果。测得的光收集不均匀性表明需要从全息检测器元件的两侧读出。
