Abstract
To compensate for the distortion of the loop-flight electric field with a higher level of accuracy, a multiturn time-of-flight mass spectrometerincludes: a main electrodeconfigured to generate, within a predetermined loop-flight space, a loop-flight electric field which is an electric field that makes an ion fly in a loop orbit multiple times, the main electrode having an openingorthrough which ions are introduced into or extracted from the loop-flight space; a compensating-electrode attachment partmade of an insulating material and fixed to the main electrode; and a compensating electrodeconfigured to compensate for a distortion of the loop-flight electric field which occurs in the vicinity of the opening, the compensating electrode being fixed to the compensating-electrode attachment part directly or via a substrateand located in the vicinity of the opening.
