Because atoms with the same charge repel,
With the good coherence of internal resistance, capacity and floating charge , there is no equalizing charge required during use.
The first mass filter stage transmits only ions having a sub-range of mass-to-charge ratios including a selected mass-to-charge ratio.
Correction coefficient is important to electric charge refund, but its power factor Angle is unknown.
With sufficient forward bias, the diffusion capacitance can easily exceed the space charge region capacitance.
