| Abstract: | In order to make the data format of NBI (Neutral Beam Injection) system compatible with EAST data and to make international exchange of experimental results effectively, an NBI data acquisition system based on MDSplus (Model Drive System plus) is developed. Double buffer technology and multi-thread mechanism are adopted in data acquisition module to achieve continuous and long-pulse data acquisition. Data storage module selects MDSplus and jScope which can access the experimental data and is packaged in MDSplus''s program developing tools to resolve the problem of unifying NBI data format and sharing NBI experimental data. The system has met the requirements of the experiment in the test and lays a good foundation for the next round EAST-NBI long-pulse injection experiments. |
