Pellet and Supersonic Molecular Beam Injection Fuelling on the HL-1M Tokamak

摘要

An eight-shots pellet injection (PI) and a supersonic molecular beam injection (SMBI) system have proposed and developed on the HL-1M tokamak for advanced fuelling experiments. The peaked density profile and improved confinement are typical feature of PI and SMBI discharge. It strongly depends on the wall recycling conditions of the HL-1M tokamak and injection parameters.
