1. A radiation particle strike detection system comprising:
a radiation particle detector including a three-dimensional structure that overlays a volume of a payload that is sensitive to interaction with radiation particles, the three-dimensional structure including a plurality of two-dimensional structures overlayed on different surfaces of the payload, the radiation particle detector configured to undergo a change in state responsive to a radiation particle strike at a location on a two-dimensional structure of the plurality of two-dimensional structures of the radiation particle detector; and
a controller coupled to the radiation particle detector and configured to:
monitor a state of the radiation particle detector;
detect a first location of a radiation particle strike on a first two-dimensional structure of the radiation particle detector based on a change in state of the radiation particle detector;
detect a second location of the radiation particle strike on a second two-dimensional structure of the radiation particle detector based on a change in state of the radiation particle detector; and
determine a location of the radiation particle strike on the payload based on a spatial correlation between the first location on the first two-dimensional structure and the second location on the second two-dimensional structure of the radiation particle detector and a time of the radiation particle strike based on the change in state of the particle detector.
