Abstract
Neutron and Gamma detectors have been used to monitor the nuclear radiation in the environment (Jianping in Nucl Electron Detect Technol 19(1), 1999; Chai et al. in Nucl Electron Detect Technol 25(1), 2005), during the experimental advanced superconducting tokamak (EAST) discharging. This paper is focus on the EAST’s nuclear radiation monitoring. Based on the full and real-time need for monitoring of radiation, the placement of radiation’s detectors around the EAST and the environment is studied. To get the radiation’s value, this paper gives the design of the monitoring system and presents the system’s acquisition module which transforms radiation to voltage signal. For the long distance and uneven distribution of each detector, transforming and processing module is designed, and the comparator’s principle and RS-485 transmission protocol are reviewed, the circuits of the comparator and RS-485 used in this system are designed. Then a conversion module is presented to have communication with personal computer, and framework of the whole monitoring system is introduced.
