## Content

The radio frequency driven source for negative hydrogen ions, to investigate the physics of production and extraction of the H$^-$ ions, is under construction at Huazhong University of Science and Technology. Plasma generated from RF driver expands to the surface of plasma grid. Extraction system with three grids is designed to extract and accelerate the H$^-$ beams. The design parameters of the ion source are: beam current 0.35 A; extraction voltage: 10 kV; accelerator voltage: 20 kV; pulse length<10 s; H$^-$ current density: 0.25 mA/mm$^2$.
