This paper provides measurements which may be used to test numerical models of ion extraction using two multiple-hole grids. A grid set, in which an isolated gridlet was embedded in an accelerator grid, was built to measure ion-impingement current distribution. The gridlet comprised both a barrel and downstream electrodes, electrically isolated from each other and the rest of the accelerator grid. The obtained measurements of ion-impingement currents on the electrodes can be directly compared with numerical predictions and they suggest an idea of possible ion flow. The results are shown as functions of screen and discharge voltages, and a hypothesis was proposed to explain a phenomenon on ion extraction.
