Abstract:

The guiding of highly charged ions through nanocapillaries in different insulating materials, such as polyethylene terephthalate, SiO₂, and Al₂O₃ has been investigated by our group, using 7 keV Ne⁷⁺ ions. We find transmission of ions incident at angles larger than the angle given by the capillary aspect ratio in all these materials. The measured angular distributions, however, vary with the membrane material. In this report we compare the experimental findings with the different membranes. PACS Nos.: 79.20.Rf, 34.50.Dy, 81.07.De

Notre groupe a utilisé des ions Ne⁷⁺ de 7 keV pour étudier le guidage d'ions hautements chargés dans les nanocapillaires de différents matériaux isolants, comme le terephthalate de polyéthylène (PET), le SiO₂ et le Al₂O₃. Nous observons la transmission d'ions incidents à des angles plus grands que les angles formés par l'aspect du capillaire dans tous ces milieux. Les distributions angulaires mesurées varient cependant avec le matériau de la membrane. Nous comparons ici les résultats expérimentaux obtenus avec diférentes membranes.[Traduit par la Rédaction]
