	Source of negative hydrogen ions for the implementation of multiturn charge-exchange injection to increase the intensity of IHEP buster is developed. Surface-plasma ion source with Penning discharge is selected as a source of H-minus ions. A high-current extraction system with downstream electron dumping has been designed. A three-dimensional ion optical code IBSimu has been utilized for modelling and optimization the extraction system and ion beam acceleration to energy of 100 keV. A magnetic low energy beam transport line consisting of two solenoids has been designed to match the beam with RFQ. TRACE 2D code was used to optimize LEBT. A deflecting magnet with small angular deflection (10) has been installed between solenoids to eliminate forward tracing of neutral atoms from ions source to RFQ.
