Abstract
A position sensitive fast timing detector for determining time-of-flight mass analysis and position of atomic particles includes a channel plate assembly for detecting the impact of one or more atomic particles a transforming them into one or more electron clouds. The electron cloud then passes through an electron detector which includes a meandric delay line located in front of a back plate. A second meandric delay line may also be utilized, wherein the second delay line is orthogonal with the first delay line. A grid may be placed between the first and second meandric delay lines to reduce cross-talk.
