Abstract

This utility model discloses an electrode lens assembly with ion deceleration and focusing, comprising an injection electrode, a first deceleration electrode, a second deceleration electrode, an acceleration electrode, and a third deceleration electrode arranged in segments along the axial direction of a fixed sleeve. The length ratio of each electrode effectively decelerates the ion beam and ensures ion focusing during deceleration, enabling efficient transmission of decelerated ions to the ion trap plasma confinement device. A protruding ring is provided on one side of each electrode, and the protruding ring of each electrode extends into another electrode, so that the uncertain potential of the insulator can no longer interfere with the potential on the central axis of the lens assembly, thereby achieving the effect of shielding external potential field interference and ensuring the stability of the ion transmission channel potential and the structure.
