In the framework of the ITER Control Breakdown Structure (CBS), Plant System Instrumentation & Control (I&C) defines the hardware and software required to control one or more plant systems [1]. For diagnostics, most of the complex Plant System I&C are to be delivered by ITER Domestic Agencies (DAs). As an example for the DAs, ITER Organization (IO) has developed several use cases for diagnostics Plant System I&C that fully comply with guidelines presented in the Plant Control Design Handbook (PCDH) [2]. One such use case is for neutron diagnostics, specifically the Fission Chamber (FC), which is responsible for delivering time-resolved measurements of neutron source strength and fusion power to aid in assessing the functional performance of ITER [3]. ITER will deploy four Fission Chamber units, each consisting of three individual FC detectors. Two of these detectors contain Uranium 235 for Neutron detection, while a third ?dummy? detector will provide gamma and noise detection. The neutron flux from each MFC is measured by the three methods: ? Counting Mode: measures the number of individual pulses and their location in the record. Pulse parameters (threshold and width) are user configurable. ? Campbelling Mode (Mean Square Voltage): measures the RMS deviation in signal amplitude from its average value. ? Current Mode: integrates the signal amplitude over the measurement period | |
