本文介绍了HL-2A装置上的扩展邦纳球能谱仪（EBSS）。该装置是在原有的Bonner球谱仪（BSS）的基础上发展起来的，目的是在HL-2A托卡马克大厅获得更精确的中子能谱。以前的BSS包含八个邦纳球（BS）。该EBSS包含13个嵌入在聚乙烯球（PS）中的3 He填充探测器、前置放大器和并行处理数据采集系统（DAQ）。在Geant 4中模拟响应矩阵，考虑环境的影响。
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 3He-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.
