| 摘 要： | 给出了氦冷却固体增殖剂中子学和产氚包层模块(NT-TBM-HCSB)聚变中子诊断的初步设计,提出了用固定或可移动位置微型裂变室探测器和可移动封装薄箔活化分析系统测量中子倍增器之后、固体氚增殖剂中及其后的中子通量;用可移动天然金刚石探测器的紧凑型能谱仪测量中子能谱。此诊断系统可用于中子倍增器的倍增效率,氚增殖层的增殖率与热核实验聚变堆的运行参数、加热和加料方式、磁流体不稳定性、能量约束以及大破裂等离子体参数和状态之间的工程和物理相关关系的实验研究,测量倍增层、氚增殖包层及其后进入屏蔽层的中子通量和能谱,并与MCNP计算相比较,优化和改进中子倍增器、氚增殖包层以及屏蔽层设计,提高氚增殖率。

| Abstract: | A basic design of neutron fluxes and spectra diagnostic at beryllium multiplier and tritium breeder in neutronics and tritium production test blanket module (NT-TBM) during D-D and D-T phases in ITER is proposed. This is important for studying and assessing capabilities of beryllium multiplier and tritium breeder in the NT-TBM of China helium cooled solid breeder (CH HCSB). This system includes encapsulated foil activation sub-system, micro-fission chamber detector (MFC) assembly, and a compact neutron spectrometer as natural diamond detector (NDD). |

| Keywords: | Neutronics and tritium production test blanket module Fission chamber detector Encapsulated foil activation system |
