title: Multichannel (e,2e) apparatus.
abstract: We describe an apparatus for the coincident observation of both outgoing electrons in an electron impact ionization, or (e,2e), experiment. The device employs ten detectors arranged such that every pair corresponds to a different set of momenta for the outgoing electrons intercepted by that pair. By simultaneously monitoring the output from all ten detectors it is possible to perform 25 simultaneous (e,2e) experiments. The results of these experiments can be compared without considering temporal variations of source conditions.
