Claim 4:
5. A vacuum electron device, comprising:
a plurality of electrically conductive sections of interaction structure housing an electron beam tunnel of the VED, the electron beam tunnel having a longitudinal axis parallel to the interaction structure;
the plurality of sections separated by pairs of electrical insulators, each pair sandwiching at least one electrostatic lens element disposed orthogonally to the longitudinal axis; and
each electrostatic lens element provided with at least one electrically conductive path to an exterior of the interaction structure, the electrically conductive path electrically insulated from the interaction structure so that a voltage applied to the electrically conductive path will be conducted to the electrostatic lens element;
wherein,
the electron beam tunnel region is surrounded by at least one magnet arranged to confine an electron beam within the electron beam tunnel.
