Abstract

The setting up of RF based negative ion experimental facility shall witness the beginning of experiments on the negative ion source fusion applications in Huazhong University of Science and Technology, China. At the current development stage, we have built a RF driver which will produce the plasma required for yielding negative ions. The experimental system is similar to a RF based negative ion source, BATMAN, presently operating at IPP but not identical. The operation of driver is supported by many subsystems e.g. vacuum pumping system with gate valves, cooling water system, gas feed system, RF generator, data acquisition, control system, and different diagnostics. Most of them were completed on schedule. Some diagnostics are proposed to measure different plasma parameters in the driver and the expansion volume. A Langmuir probe and an OES is used in this facility. Some main diagnosis is shown in this paper.
