For the cooling of proton and Ion beams a well established overlap between cooling beam and circulating beam is needed. The new relativistic electron cooling devices have special demands on the diagnostics which can be used to characterize the cooling beam. Due to high voltage breakdowns they only allow a very small beam loss so non-invasive beam diagnostic methods are necessary. A system based on beam induced uorescence (BIF) was installed at the 100 keV polarized test setup at the Mainzer Mikrotron (MAMI). First results of the measured photon yield as a function of beam current and residual gas pressure will be presented. In addition a Thomson scattering experiment is planned at the same test setup. This method enables the measurement of other observables of the cooling beam like the electron beam energy or the electron temperature. The design of the experiment as well as the challenges will be discussed.
