NSCL Seminar Room

Diagnostics of intense particle beams require the development of new non-invasive beam monitoring methods. For hadron beams three methods have been found to be the most promising. Two methods use the interaction of the hadron beam with the residual gas, with the result of the residual gas molecule either gets ionized or sends out a photon. The third one uses the Coulomb force by crossing another charged particle beam with the primary beam. For certain conditions the usage of the luminescence is the preferred method, despite its rather low cross section. A general overview of non-invasive beam profile measurements will be given and the parameters when residual gas luminescence is the best option discussed. In addition working setups and successful measurements at the Forschungszentrum Juelich (Germany), the iThemba LABS (South Africa) and the GSI (Germany) will be presented.
