Abstract

The present disclosure provides electrode portions for generating electric and/or magnetic fields for trapping ions in a trapping zone, a three-dimensional (3D) ion trap including one or more of such electrode portions, systems for trapping ions with such a 3D ion trap, as well as methods for manufacturing such electrode portions. An electrode portions includes an electrode body made of an electrically insulating substrate and elongated in a first direction towards the ion trapping zone, a peak electrode located on an extremity of the electrode body closest to the trapping zone or a side electrode located laterally relative to the extremity, and a connection connected to the peak electrode and leading from the peak electrode through said electrode body away from the trapping zone.

Dependent claims

A three-dimensional ion trap comprising a plurality of electrode portions for trapping ions in a trapping zone, wherein at least one electrode portion of said plurality of electrode portions comprises:

an electrode body comprising an electrically insulating substrate and comprising a portion extending in a first direction towards the ion trapping zone;
a peak electrode located on an extremity of the electrode body closest to the trapping zone;
a side electrode located on the electrode body laterally of the extremity;
and
a connection connected to the peak electrode or to the side electrode and leading through said electrode body away from the trapping zone, wherein a width of said portion of the electrode body in a second direction, which is perpendicular to the first direction and to a third direction along the ion trapping zone, decreases along the first direction towards the ion trapping zone.
