To demonstrate the function of a gas sheet for measuring the 2D profiles of accelerated beams, the following experiments were performed: 1) A gas sheet with a thickness of 1.5 mm and a density of 2×10−4 Pa was produced by the deep slit, and the shape of the sheet was improved by the thin slit. 2) For an electron beam of 30 keV and a diameter greater than 0.35 mm, the position and the 2D profiles were appropriately measured using the gas sheet.
