Abstract

Real-time Bonner sphere spectrometry (BSS) at the HL-2A tokamak for the neutron spectrum diagnostic is described. The spectrometer consists of eight different size Bonner spheres made of polyethylene and with a 3helium-filled detector in the center, pre-amplifiers, and parallel-processing data acquisition system (DAQ). Dynamic neutrons from plasma discharges of the HL-2A tokamak were measured and the real-time neutron spectrum was presented.
