    Graphical Abstract
    • Abstract
  • The time-resolved neutron flux density measurement system on HT-7 Tokamak is presented in the paper. When the machine is operated in high performance mode, the total neutron yield is estimated to be about 10~8 s~(-1), and the neutron flux density near the vacuum vessel is about 10~2 cm~(-2)·s~(-1). Therefore, BF_3 proportional counter based system was constructed and successfully implemented on HT-7. The measurement system works stably during a series of experiments. The measured neutron flux density is in agreements with that from the numerical estimation.
