The Low Energy High Intensity Proton Accelerator (LEHIPA) is a 20 MeV 30 mA proton accelerator which will be achieved in multiple stages. LEHIPA consists of several sub systems/devices located at different positions of the beam path which includes ION source , RF Power , RF Protection Interlock System, Low Conductivity Water plant, Low Level RF control Systems, Vacuum System, Beam Diagnostics & Beam Line Devices. All these subsystems have their own local control systems (LCS) which will coordinate the operation of the corresponding subsystem. The control system for LEHIPA is thus being designed as a Distributed Control System with different teams developing each LCS. The control system will assist the operator to achieve a beam of desired characteristics by interacting with various sub systems of the accelerator in a seamless manner,protect the various parts machine by generating the necessary interlocks ,keep track of various parameters monitored periodically by suitably archiving them, alarms annunciation and trouble shoot from the control room. This paper describes approach to system design of ICS.

An RF control system has been developed for the 400 keV, 350 MHz RFQ coming up at BARC. This single cavity system consists of the functionalities of amplitude stabilization and frequency tracking for both continuous and pulsed mode of operation. The amplitude stabilization is implemented by modulating the attenuation across a fast modulator placed in the drive path. The frequency tracking is achieved by driving the FM port of a signal generator with a signal proportional to the phase shift across the resonator. The whole system is under computer control via CAMAC hardware. The paper describes the system architecture, housing & wiring of the system in a single instrumentation rack and development & testing of computer control.
