Abstract:
1. An ion optical assembly comprising: a mounting body having a front side and a back side; a front securing member having a threaded surface and a contact face; a front member having a threaded opening configured to accept the threaded surface of the front securing member, the front member being attached to the mounting body by at least one attachment member; and a first plurality of ion optical elements disposed between the front side of the mounting body and the front member, each ion optical element of the first plurality having a recess structure adapted to receive a complimentary registration structure, a registration structure aligning an ion optical element of the first plurality with respect to at least one other ion optical element of the first plurality when said registration structure is registered in a complimentary recess structure by application of a compressive force by the front securing member against the first plurality of ion optical elements; wherein the threaded opening of the front member is configured such that when the threaded surface of the front securing member is engaged in the threaded opening of the front member, the contact face of the front securing member can contact an ion optical element of the first plurality and apply a compressive force against the first plurality of ion optical elements.
