Molecular beam set-up = MESO-m3a

Molecular beam techniques provide a well established method for measuring cross sections of collision processes and investigating reaction dynamics in the electronvolt range [The context is sketched in the mesoscopic <i>Situation</i> module (link type: 'context in/project'; target: MESO-m2a]. A typical set-up for a molecular beam experiment consists of the following components. The first collision partner is prepared in a primary beam, which is generated in a source and filtered with respect to the state of the particles in a (velocity) selector. The second collision partner is prepared in a secondary beam, a static target, or a hybrid. These collision partners collide in an interaction region. The reaction products are analysed (i.e. the different types of products are separated) and the products relevant to the research at hand are measured in a detector. 1
