The 6.4 MeV 15 N 2+ ion beams are focused using glass capillary optics. The transmitted beam includes ions which have suffered slight energy loss. The areal density of the transmitted beam is enhanced by approximately 10 times, and the enhancement factor does not depend on the incident beam current.

A novel technique to introduce high energy ion beams to atmospheric environment is presented, which enables in-air PIXE measurements. Slightly tapered glass capillary optics is applied to work as a differential pumping orifice as well as a focusing lens. The flux intensity is enhanced by at least on
