The PRESPEC-AGATA setup is a unique combination of the GSI accelerator facility, the Fragment Separator(FRS), the Advanced Gamma Tracking Array(AGATA), the HECTOR array and the LYCCA-0 Calorimeter. With this setup high-resolution in-flight spectroscopy of relativistic(β∼0.4-0.5) exotic nuclei will be performed. A thick target positioned at the final focal plane of the FRS will be used for Coulomb excitation or fragmentation of the exotic ions separated with the FRS. The γ-rays emitted in these reactions will be detected by the AGATA and HECTOR arrays. The fragments produced at the secondary target will be identified and tracked by LYCCA-0. Compared to the RISING array, the improved energy resolution and efficency of the AGATA array is expected to lead to a gain in sensitivity of a factor of 10 and 100 for γ-particles and γ-γ-particle coincidences, respectively. The perspectives of the new setup will be discussed. Supported by the BMBF under 06DA9040I, by HICforFAIR, and by the HGF under VH-VI-417.
