Space-charge compensated high-perveance ion beams are of main interest for the injection into RFQ systems. Space-charge compensation enhances the maximum transportable current in low energy beam transport lines which is mainly limited by space-charge forces. The compensation electrons are usually produced by residual gas ionisation. In this case beam pulses reach the final degree of compensation after a certain time. To investigate the compensation processes of a periodically decompensated
