	A system of remote control of surface plasma source of negative ions for INR RAS LINAC was designed, constructed and put into operation. The INR LINAC negative ions injector is based on the accelerating tube at energy of 400 keV and surface plasma source of negative ions. Galvanic isolation and spatial separation of elements that are at potential 400 kV in the power rack of the ion source and the host computer are carried out by means of fiber-optic USB-interface extender from firms Icron. A set of multifunctional units from National Instruments allows to monitor the oscilloscope signals with up to 50 Ms/s and to control the ions source power settings. The data acquisition devices programming performed in a LabView graphical environment. Algorithm and LabVew code for fast and safe "conditioning" of the ion source discharge gap and extractor gap from arcing and breakdowns were developed.

	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 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.

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.
