The system is developed for control of the neutral beam injector which operates with 15-25 keV deuterium and hydrogen beams of 2 s maximum duration. It performs injection parameters calculation according to the desired beam power vs time curve, synchronizes and protects the injector subsystems and acquires its data during the shot. It also controls the injector operation between the shots. The system is based on an industrial computer with National Instruments PCIe boards: two PCIe-7842R reconfigurable input-output modules and a PCIe-6323 data acquisition module. An in-house developed interfacing module (cross-box) as well as serial to fiber optic converters are used for galvanic isolation and electrical compatibility with the injector subsystems. User interface software and PCIe boards programmable logic firmware are implemented in LabVIEW. Injection calculations and results acquired are represented with MATLAB.
