Assembling and testing of liquid scintillation detectors on the EAST neutron camera

A new neutron camera, comprising twelve individual liquid scintillation detectors, was designed for the Experimental Advanced Superconducting Tokamak (EAST). Twelve assembled neutron detectors will be installed onto the neutron camera, with seven detectors forming a horizontal camera and five detectors forming a vertical camera. These detectors play the main function of measuring the 2.45 MeV neutron emissivity profile. The 2 " x 2 " BC501A liquid scintillation detector coupled with the gain stabilization system has been developed for neutron measurements and would be applied to the camera. The Assembling and testing of detectors were discussed in details in the second section of this manuscript. The data acquisition system that can automatically acquire neutron information was developed and described in the third part.
