Description

Interaction of 30 keV O3+ ions with capillaries in an Al2O3 membrane was studied. The charge state distribution and the angular distribution of the ions transmitted through the capillaries were measured. Shifts of the transmission profile centroid by twice of the capillary tilt angle ψ and double-peak structure in the transmission profile were found. Difficulties exist in determination of the impact point location on the capillary wall and the scattering angle for each collision to interpret the observed 2ψ shift phenomenon. The transmission profile width and ion guiding ability of the concerned capillaries for the used projectile ions were analyzed. Comparison of the present guiding angle and the prediction of scaling laws was conducted. Further work concerning the influence of the material and its surface treatment on the guiding properties is needed
