Abstract

Two-dimensional temporally resolved beam diagnostic method for intense ion beams, intended for ion beam fusion, is developd This is an extension of one-dimensional Arrayed Pinhole Camera (APC) with time integrated detector [K.Yasuike, S. Miyamoto and S.Nakai, Review of Scientific Instruments, (to be published).] A two-dimensional correlation analysis of the arrayed images yields an intensity distribution and an angular two-dimensional distributions (beam divergence) of pulsed ion beam. A temporal resolution is obtained by using a gated micro channel plate (MCP) as a time resolved ion detector, Achieved spatial and angular resolutions are smaller than 1 mm and better than 20 mrad, respectively. A temporal resolution is about 15 ns that is determined by a width of the gating pulse and a MCP gain characteristic. This two-dimensional APC was successfully tested on a magnetically insulated pulsed ion diode, which generates an annular Proton [H^+] beam of energy 1 MV, current density of -10 A/cm^2,pulse duration of 100 ns. The results show that the ion beams accelerated by the magnetically insulated diode have direction-dependent beam beam divergence.
