We studied blocking effects on 3-keV Ne7+ ion guiding through nanocapillaries in highly insulating polyethylene
terephthalate (PET) manufactured at different laboratories. The experiments were motivated in
view of previous measurement with PET capillaries prepared at the GSI Helmholtz-Zentrum for which
significant blocking effects were observed, whereas in various previous studies with PET capillaries these
effects could not be detected. As the blocking effect on the GSI capillaries strongly depends on their areal
density, similar dependencies were studied with the FLNR capillaries. Long-term stable transmission was
observed for all densities of the FLNR capillaries in contrast to the previous results. These observations are
interpreted by differences in the capillary surface conductivities in accordance with charge patch formations
within the capillaries. It is pointed out that the observed stable transmission is favorable for applications
of ion guiding in capillaries.
