Focusing of intense ion beam by the “Inverse Pinch Ion Diode”

Focusing of intense ion beams has been attained with the “Inverse Pinch Ion Diode” which has a flat anode. The energy of the ion beam was 180 keV. At the focal point, the ion current density of 0.5 kA/cm
²
has been obtained and the focusing radius of the ion beam (FWHM) is 10 mm. Focusing of the ion beam is due to the electrostatic field in the “Inverse Pinch Ion Diode”.
