Ion integrating and cooling cell for mass spectrometer

An apparatus, comprising:

• a plurality of first apertured thin electrodes disposed in a stacked relationship relative to one another, each first apertured thin electrode comprising a respective plane having a respective first aperture therein, the plurality of first apertures defining a first ion conduit, the first ion conduit defining an ion pathway through a portion of the apparatus, said ion pathway being transverse to the planes of the first apertured thin electrodes;
• a plurality of second apertured thin electrodes disposed in a stacked relationship relative to one another, each second apertured thin electrode comprising a respective plane having a respective second aperture therein, the plurality of second apertures defining a second ion conduit, the second ion conduit defining a second ion pathway through a second portion of the apparatus, said second ion pathway being transverse to the planes of the second apertured thin electrodes;
• a plurality of third apertured thin electrodes disposed in a stacked relationship relative to one another and disposed between the plurality of first apertured thin electrodes and the plurality of second apertured thin electrodes, each third apertured thin electrode comprising a respective plane having a respective third aperture therein, the plurality of third apertures defining a curved third ion conduit disposed between and non-coaxial with the first and second ion conduits, the third ion conduit defining a third ion pathway through a third portion of the apparatus, said third ion pathway being transverse to the planes of the third apertured thin electrodes;
• a plurality of fourth apertured thin electrodes disposed in a stacked relationship relative to one another and disposed between the plurality of first apertured thin electrodes and the plurality of second apertured thin electrodes, each fourth apertured thin electrode comprising a respective plane having a respective fourth aperture therein, the plurality of fourth apertures defining a curved fourth ion conduit disposed between and non-coaxial with the first and second ion conduits, the fourth ion conduit defining a fourth ion pathway through a fourth portion of the apparatus, said fourth ion pathway being transverse to the planes of the fourth apertured thin electrodes;
• and
• an electrical power supply electrically coupled to each apertured thin electrode of the first plurality, second plurality, third plurality and fourth plurality of apertured thin electrodes and configured to apply an oscillatory radio-frequency (RF) voltage and a respective direct-current (DC) voltage to each of said apertured thin electrodes, such that, within each stacked relationship, a phase of the RF voltage applied to each apertured thin electrode differs by π from the phase of each adjacent apertured thin electrode.
