Abstract
Abstract 1. A method for obtaining a thinner zone in a resonator blade by ion bombardment using an iris, characterized in that the iris (1, 31) presents an edge zone (12, 33) around its opening (2, 32) which is shaped such that during the bombardment, this edge zone is at least partially consumed and causes the opening (2, 32) of the iris (1, 31) to be enlarged such that a step (22, 23, 26, 42) is obtained between the thinner zone (25, 44) and the remaining blade (20, 40).
