"Classical" Crossed Beam Instrument

Mass Spectrometry Divission at the University of Delaware

These Instruments started a new era in experimental chemical dynamics in late 1970's. And nothing is trivial about them even nowdays. Each machine of this kind has it's own features and original tricks in terms of design and realization. And so has our one.

The general idea of a Crossed-Beam Experiment is to collide the two beams of known chemical species (in our machine the ion beam provided by sector MS is collided with molecular beam) with a well known energy. Going around the collision point with an energy-analyser/Mass analyser Detector we collect information about the chemical composition and energy of the fragments of ion-molecule reaction.

This instrument became a textbook one as an elegant combination of physics ideas implemented in design for analytical chemistry.
