Slicing Newton spheres with a two-camera 3D imaging system.

Abstract

We demonstrate a simple approach to achieve three-dimensional ion momentum imaging. The method employs two complementary metal-oxide-semiconductor cameras in addition to a standard microchannel plates/phosphor screen imaging detector. The two cameras are timed to measure the decay of luminescence excited by ion hits to extract the time of flight. The achieved time resolution is better than 10ns, which is mainly limited by camera jitters. A better than 5ns resolution can be achieved when the jitter is suppressed.
