Abstract
A gating grid for deflecting ions includes an insulating substrate (), a conducting layer () adhered to the insulating substrate (), and interdigitated electrodes () patterned in the conducting layer by a photolithographic process. A hole () in the insulating substrate beneath the interdigitated electrodes allows ions to pass through the hole in the substrate. A process for making a gating grid for deflecting ions includes adhering a conducting layer () to an insulating substrate (), forming interdigitated electrodes () on the conducting layer (), and then forming a hole () in the insulating substrate beneath the interdigitated electrodes.
