Velocity map photoelectron-photoion coincidence imaging on a single detector. Lehmann, C S., Ram, N B., & Janssen, M. H M The Review of scientific instruments, 83(9):093103, September, 2012. ![Velocity map photoelectron-photoion coincidence imaging on a single detector. [link]](https://bibbase.org/img/filetypes/link.svg "link")
Paper doi abstract bibtex Here we report on a new simplified setup for velocity map photoelectron-photoion coincidence imaging using only a single particle detector. We show that both photoelectrons and photoions can be extracted toward the same micro-channel-plate delay line detector by fast switching of the high voltages on the ion optics. This single detector setup retains essentially all the features of a standard two-detector coincidence imaging setup, viz., the high spatial resolution for electron and ion imaging, while only slightly decreasing the ion time-of-flight mass resolution. The new setup paves the way to a significant cost reduction in building a coincidence imaging setup for experiments aiming to obtain the complete correlated three-dimensional momentum distribution of electrons and ions.
