Abstract Recent experiments showed that the incomplete guiding appears when intermediate energy ions pass through a macrocapillary (Wu et al., 2014). In order to further explore this effect, experiments and simulations for 90 keV Oq+ ions ( q = 6, 5, 3) passing through a glass macrocapillary are performed. It shows that the incomplete guiding is understood by the formation of an insufficient charge patch in the capillary entrance region due to the bulk conductivity producing a significant charge loss.
