Abstract
A method for cluster fragmentation comprises the production of at least one cluster which contains a carrier substance and the fragmentation of the cluster into cluster fragments, with the cluster being loaded before the fragmentation with at least one reaction partner and the reaction partner being part of at least one cluster fragment after the fragmentation. A cluster beam system for performing the method, and applications of the cluster fragmentation for analysis and purification of surfaces, for analysis of clusters, and for the operation of ion thrusters are also described.
Claims30
A method for cluster fragmentation comprising the steps:
- producing a neutral cluster comprising a carrier substance comprised of polar molecules, said cluster comprising at least 10 of said polar molecules, loading said neutral cluster with at least one reaction partner, said step of loading said cluster comprises the step of applying neutral molecules as an absorbate coating to a solid body surface, said reaction partner being chemically different from the carrier substance, said at least one reaction partner forming at least one pair of electrically differently charged charge carriers with the carrier substance in the cluster, either spontaneously or excited from the outside, and fragmenting the cluster into a plurality of cluster fragments, such that at least one positively charged and at least one negatively charged cluster fragment is formed during the fragmentation, and the at least one reaction partner is part of at least one cluster fragment after the fragmentation, and the cluster fragments are spatially separated.
