The Institut für Kernphysik in Münster developed an XUV-photon detection system for laser spectroscopy measurements at the ESR. In a test beam time for laser cooling with 12C3+-ions at β≈0.47, the 2S1/2−2P1/2 transition was investigated to commission the system. The detector features a movable cathode plate which is brought into the vicinity of the beam to collect forward emitted Doppler shifted photons (λlab ≈ 93 nm). The photons produce mostly low energetic (<3 eV) secondary electrons which are electromagnetically guided onto an MCP detector. First results of the beam time will be presented. This work is supported by BMBF under contract number 05P15PMFAA. D. Winzen thanks HGS-HIRe for FAIR for funding his scholarship.
