  Slow extraction of beam from synchrotrons or storage rings as required by
many fixed target experiments is performed by controlled excitation and feeding
of a structural lattice resonance. Due to the sensitive nature of this resonant
extraction process, the temporal structure of the extracted beam is modulated
by the minuscule current fluctuations present on the quadrupole magnet power
supplies. Such a modulation lead to pile-ups in detectors and a significant
reduction in accumulated event statistics. This contribution proposes and
experimentally demonstrates that by an introduction of further modulation on
quadrupole currents with a specific amplitude and frequency, the inherent power
supply fluctuations are mitigated leading to a smoothening of the beam temporal
structure. The slow extraction beam dynamics associated with this method are
explained along with the operational results.
