The Compact toroid CT fueler of SPICA (SPheromak Injector using Conical Accelerator) for LHD has been developed at NIFS. Recently, in order to apply CT injection technique to more effective fueling, production and injection of super-high speed neutral particle flow (NPF) have been studied. The NPF injection has a potential ability to fuel more effectively than supersonic gas jet and can play a specific part beyond neutral beam injection. We have then proposed a fueling system of CT-based NPF injection and launched experiment on production of super-high speed NPF by using the SPICA injector.
