Multi-Channel Neutron Emission and Triton Burn-up Measurement on JT-60U Using Digital Signal Processors

In JT-60U, the multi-channel neutron profile monitor measures the line-integrated neutron emission. A digital signal processing (DSP) system was applied to all neutron detectors in the neutron profile monitor. A new 2D mapping method for DSP data analysis was developed to discriminate neutrons from...

Zusammenfassung:In JT-60U, the multi-channel neutron profile monitor measures the line-integrated neutron emission. A digital signal processing (DSP) system was applied to all neutron detectors in the neutron profile monitor. A new 2D mapping method for DSP data analysis was developed to discriminate neutrons from γ-rays. The combination of DSP and the 2D map enabled the simultaneous measurement of DD and DT neutrons with one detector. The time evolutions of DD and of DT neutrons showed different responses to the ITB formation, depending on the viewing chord.
