space charge effect

https://doi.org/10.1351/goldbook.12577
Result of mutual repulsion of particles of like charge (ions, electrons, etc.) that can limit the current in a charged-particle beam and can also cause some motion of ions in a beam or packet in addition to that caused by external fields.
Note: Space charge effects on ion trajectories are most noticeable in ion trap instruments that confine large numbers of ions in a small volume.
