北京正负电子对撞机(BEPC)同步辐射实验厅辐射剂量水平的测定

Measurement of Radiation Dose Level of Synchrotron Radiation Experimental Hall of BEPC

本文描述了北京正负电子对撞机(BEPC)同步辐射实验厅内辐射的来源和特点,辐射测量方法及其测量结果。通过对东、西两个实验厅的辐射剂量水平随时间和空间变化的分析,得出一个重要结论:同步辐射实验厅内辐射剂量水平与实验厅相对正负电子束流注入点的位置、屏蔽墙厚度、束流注入的时间和效率有密切关系。

This paper describes the radiation source and its characteristics of the Synchrotron Ra^- diation Experimental Hall of BEPC, the radiation measuring method and measured results. It has been found that the radiation dose level of the Synchrotron Radiation Experimental Halls is closely correlative with the relative location of the Experimenta1 Halls to the injection points of the electron and positron beams, the thicknesses of the shielding walls, the times and effi- ciencies of the beam injections.
