Present Status of ITER Neutron Diagnostics Development
- 74 Downloads
Neutron diagnostic systems are needed to monitor some important ITER parameters, such as fusion power, power density or ion temperature. The aim of this paper is to describe various systems, such as neutron cameras, internal and external flux monitors, activation system and spectrometers. Also, the current status of in situ neutron calibration strategy is reported. ITER is currently under construction in Cadarache (France) and neutron diagnostic systems are progressing from design stage to manufacturing.
