BESⅢ晶体量能器累积剂量检测系统电子学设计

Design of Readout Electronics for BESⅢCrystal Calorimeter Integrated Dose Monitoring System

为了在线测量北京谱仪BESⅢ中的量能器所受到的辐射累积剂量,设计了BESⅢ量能器累积剂量检测系统。讨论了几种RADFET受照电路的优缺点,介绍了RADFET读出电路,并详细叙述了系统电子学的设计及其性能。

BESⅢ crystal calorimeter integrated dose monitoring system has been designed in order to measure the integrated close near BESⅢ crystal calorimeter. The advantages and disadvantages of several radiation circuits are discussed at first. RADFET readout circuit for one RADFET ehannel is then introduced. The design and performance of system electronics are finally illustrated in detail.
