This paper reports on the development of a new experiment for the study of
electron-impact induced dissociation and fragmentation of molecular clusters and biomolecules
and other species solvated in water clusters. The purpose is to look at clusters that are of
interest to biophysics, atmospheric physics, and other fields. The experiment consists of a
differentially pumped vacuum system, with an expansion chamber to generate a pulsed
supersonic beam of clusters, and a collision chamber where the cluster beam intersects with an
electron beam. Water clusters can be seeded with biomolecules emerging from a resistively
heated oven. Investigation will be possible into both ion yields and long-lived neutral
metastable yields produced by electron-impact fragmentation of relevant clusters and
biomolecules.
