A mini review of the crossed molecular beam apparatus in molecular reaction dynamics

This review has introduced some experimental techniques of crossed molecular beam apparatus in chemical reaction dynamics. First of all, the history of crossed molecular beam equipment is retrospected in this paper. The detectors of both the universal crossed molecular beam machine and Hydrogen-atom Rydberg-tagging apparatus have been discussed. Other types of crossed molecular beam instruments have also been reviewed. Each experimental apparatus makes a compromise among the resolution, sensibility and universality. As a matter of fact, it is these equipments that make many breakthroughs happen in chemical reaction dynamics. This review aims to provide the readers and researchers with some information about the experiments in molecular reaction dynamics. We believe that new types of experimental techniques can emerge and contribute to the development of molecular reaction dynamics and relevant research fields.
