Abstract
A method for efficiently filling a QIT which isolates an ion range by employing a sequential part of supplemental broadband waveforms where the first such supplemental broadband waveform is applied during the period that the e-beam ionization bombardment takes place and the second such broadband waveform is applied after the e-beam bombardment ends.
