WebKeywords: ion beam etching, shielding rate, etch depth, parametric modeling. 1. Introduction. As a state-of-art technique, IBE plays a crucial role in the ultra-precisionfabrication of large optics such as X-ray mirrors [1], vacuum ultraviolet gratings[2], and beam sampling gratings (BSGs) [3, 4]. WebShielding surrounds the target on a linac or the source on a 60Co unit. Most regulations require this shielding to limit the leakage radiation to 0.1% of the useful beam at 1 m from the source. The adequacy of this shielding must be verified during acceptance testing. This verification may be accomplished by closing the collimator jaws and sharegate started
