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

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

   Sammanfattning : 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. LÄS MER
