  2. 2. Transmission of slow highly charged ions through nano-structures

    Author : Nadeem Akram; Reinhold Schuch; Friedrich Aumayr; Stockholms universitet; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP; Highly charged ions; nano-structures; nanocapillaries; ion-guiding; Physics; fysik;

    Abstract : This thesis is based on experimental investigations of transmitting slow highly charged ions through nano-structures of various cross-sections. Transmission through rhombic and rectangular nanocapillaries in muscovite and phlogopite mica, respectively, is used to study the guiding and shaping of highly charged ion beams. READ MORE
