A Residual Gas Monitor (RGM) developed at GANIL was tested with pulsed and CW proton beams at currents up to 1 mA at SARAF Phase I. Response of the detector as a function of beam current and duty cycle was measured. Beam profiles were measured at different beam size and position values and compared with measurements performed with a multi-wire grid profiler. Influence of the low-energy beam transfer (LEBT) optical settings on intense CW beams was studied for the first time. The obtained data enabled a better analysis and understanding of the current ramp-up process.
