【 摘 要 】

The transmission as a function of the tilt angle of a 3 keV Ar+ion beam through a conical macroscopic glass capillary is studied theoretically and experimentally. It was found that the charge patches which are responsible for the ion guiding also compress the beam spatially in the direction orthogonal to the patches, resulting into an enhancement of the transmission with increasing tilt angle.
