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

   Sammanfattning : This thesis contains experimental work on guiding of highly charged ions through insulating nanocapillaries. We have studied the time evolution of angular distributions of transmitted ions under well defined initial conditions: already charged, as well as fully discharged nanocapillaries, by using a two-dimensional position sensitive Micro Channel Plate detector with a data acquisition system working in event mode.
