Electrical Parameter Measurement System of the Ion Source for EAST Neutral Beam Injector

摘要

Neutral beam injection (NBI) is recognized as one of the most effective means of plasma heating. A virtual instrument (Ⅵ) has been designed to provide electrical parameter measurement for the ion source of EAST-NBI. The Ⅵ is written using the National Instruments LabVIEW graphical programming language. All data acquisition (DAQ) is accomplished using ADLINK DAQ hardware interface and Task-oriented DAQ Driver. The VI can measure filament voltage, filament current, arc voltage, arc current and accelerating voltage etc. The data obtained from the Ⅵ are feedback of the ion source operation state and helpful to direct the operation parameter optimization of the ion source.
