Abstract

Transmission experiments of 7-200 keV H2+ ions through conical multicapillaries with inlet or outlet diameters of 4/2 μm and a length of 30 μm etched in a PC polymer are reported. The yield of the transmitted particles as a function of the capillary tilt angle was measured. The results show that for 200 keV H2+ ions the guiding effect disappears but a focusing effect is obtained with a density enhancement factor of 3.5. For 7-50 keV H2+ ions their transmitted particle curves exhibit a pair of shoulder peaks on the left- and right-hand side of the center angle 0°. As the ion energy increases, the shoulder-peak structure is found to vanish leaving one peak at 0°.
