Summary: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 parallelprocessing data acquisition system（DAQ）.Dynamic neutrons from plasma discharges of the HL-2A tokamak were measured and the real-time neutron spectrum was presented.
