Abstract
Nanjing Proton Source (NPS) is a high-intensity superconducting accelerator large-scale scientific facility proposed by Nanjing University. As the advanced research project, a low-energy injector is going to be set up at the first stage. In consideration of stable performance and low cost, a duoplasmatron ion source is chosen to provide 50 keV, 40 mA proton beam for the downstream RFQ matching by a low-energy beam transport (LEBT). The duoplamatron is designed based on the existing plasma reservoir structure and optimized for low RMS emittance. The paper mainly describes the design work about the plasma generation system and the optimization study of a triode extraction system for minimizing the normalized RMS emittance. The simulation shows that a slightly concave plasma meniscus contributes to improving beam qualities. At present, the duoplasmatron source and beam diagnostics have been set up, and the source prototype is on commissioning.
