Abstract
Guided transmission of highly charged ions through nanocapillaries in insulating PET polymers was investigated. New PET samples with parallel capillaries were adopted using a variety of ions ranging from Ne7+ to Xe25+. The results yield new insights into the mechanisms of capillary guiding. The fraction of transmitted ions was found to be independent on the incident ion current indicating a sudden increase of the discharge current. Scaling laws for the guiding of highly charged ions are established yielding a unified curve for the projectile parameters charge state, energy and incident angle. The results are discussed in terms of the guiding power which specifies the ability of a material to guide ions.
