“…Bonner sphere spectrometry (BSS) is a neutron spectrum measurement strategy widely used in laboratories around the world, invented by Bramblett in 1960 [6]. It has been popular due to its features such as high coverage of neutron energy (from thermal to GeV), simple response functions, high sensitivity, and isotropy responses [7,8]. The spectrometer is made up of polyethylene spheres (PS) of different sizes, each with a 3 Hefilled detector embedded in the center of the sphere.…”

The extended Bonner sphere spectrometer (EBSS) at the HL-2A tokamak for the neutron spectrum is described. This device was developed on the basis of previous Bonner sphere spectrometry (BSS), aiming to obtain a more accurate neutron spectrum in the HL-2A tokamak hall. The previous BSS contained eight Bonner spheres (BS). This EBSS contains 13 3 He-filled detectors embedded in polyethylene spheres (PS), pre-amplifiers, and a parallel processing data acquisition system (DAQ). A response matrix is simulated in Geant4 taking the effect of the environment into account.
