Abstract
A method for manufacturing a miniature quadrupole from a single blank includes fastening four lengthwise insulating strips into parallel slots formed in the blank. A lengthwise axial hole is cut through the blank for the guide wire used in the EDM process. The blank is machined lengthwise into four electrodes using the EDM process so that the electrodes are spaced apart in a widthwise direction and each electrode is connected to an adjacent electrode by one of the insulating strips. During the cutting, the electrodes are held in place by the insulating strips.
Claims6
A method for manufacturing a miniature quadrupole, comprising the steps of:
- providing a single blank;
- forming slots in a surface of said blank, said slots being parallel to a long axis of said blank;
- affixing four insulating strips into said slots, one strip per slot;
- and
- machining said blank lengthwise into four electrodes such that said electrodes are spaced apart in a widthwise direction and each electrode is connected to an adjacent electrode by one of said insulating strips.
A method for manufacturing a plurality of electrodes such that each electrode is separated from an adjacent electrode by an insulating strip, comprising:
- providing a single blank;
- forming, parallel to a long axis of said blank, a plurality of slots in a surface of said blank;
- affixing a plurality of insulating strips into said plurality of slots, one insulating strip per slot;
- and
- machining said blank lengthwise into said plurality of electrodes, said plurality of electrodes being both connected and spaced apart by said plurality of insulating strips.
