Correlated ion-(ion/neutral) time of flight mass spectrometer.

The fragmentation of molecular systems into ions and neutral species is ubiquitous in fundamental and applied science. While the ion fragments are relatively easily detected by mass spectrometry technique, the information on the neutral product that is formed in correlation is challenging. In this contribution, we present a detailed description of the correlated ion-(ion/neutral) time of flight mass spectrometer, which is dedicated to the study of molecular dissociation induced by electrons at low energies (<20 eV). This new mass spectrometer uptakes the challenge to provide the correlation of ion/neural species produced in low energy electron-molecule collision processes.
