We developed multi-dimensional ion beam diagnostics system with spatially and time resolution. We used newly developed Arrayed Pinhole Camera (APC) for this diagnosis. The APC can get spatially distribution of divergence and current density. We use two type of particle detector in this study. The one is CR-39 nuclear track detector. APC with CR-39 can get time integrated images. The other one is gated Micro-Channel-Plate (MCP) with phosphor plate looked by CCD camera. It enables time resolving diagnostics. The diagnostics systems have resolution better than 10mrad divergence. 0.5mm spatial resolution on the objects respectively. The time resolving system has 10ns time resolution. The experiments are performed on Reiden-IV and Reiden-SHVS induction linac. We get time integrated divergence distributions on Reiden-IV proton beam. We also get time resolved image on Reiden-SHVS.
