Development of Data Acquisition System of Electric Parameters for Neutral Beam Injector Ion Source

The neutral beam injection(NBI) is one of the most effective heating and current driven methods. The ion source is the important part of beam line, which electric parameters are important for experimental operation and troubleshooting. In order to acquiring the experimental parameters of ion source, the data acquisition system of electric parameters of ion source for NBI has been developed. Considering the galvanic isolation, the data acquisition system must contain the function of isolation transmission. The transmission rate of the system reaches 3kHz, which meets the experimental demands absolutely. Experimental results show that the data acquisition system achieves the measurement of current and voltage signals of ion source.
