Abstract

SynopsisA new data acquisition system for electron-impact time-of-flight mass spectrometry has been set up, in which a field programmable gate array is used for the timing and the recording of mass spectra on an event by event basis. Fragmentation studies of anthracene have shown clear evidence for double ionization above 21 eV electron impact, which provides the motivation to look for coincident fragments. The first results for coincidence mass spectrometry of anthracene will be presented at the conference.
