Abstract	This report contains the Proceedings of the CARE-HHH-APD Event BEAM’07, “Finalizing the Roadmap for the Upgrade of the CERN & GSI Accelerator Complex,” which was held at CERN in Geneva, Switzerland, from 1 to 5 October 2007. BEAM’07 was primarily devoted to beam dynamics limitations for the two, or three, alternative baseline scenarios of the LHC luminosity upgrade and to critical design choices for the upgrade of the LHC injector complex at CERN and for the FAIR complex at GSI. It comprised five parts: (1) a Mini-Workshop on LHC+ Beam Performance, (2) a CERN-GSI Meeting on Collective Effects, (3) the Francesco Ruggiero Memorial Symposium, (4) a Mini-Workshop on the LHC Injectors Upgrade, and (5) the BEAM’07 Summaries. Topics addressed in the first mini-workshop of BEAM’07 ranged from the luminosity performance reach of the upgraded LHC in different scenarios, over the generation and stability of the future LHC beams, the turnaround time, beam–beam effects, luminosity levelling methods, and beam–beam compensation techniques, to advanced collimation schemes. The second mini-workshop of BEAM’07 and the integrated CERN-GSI meeting covered the superconducting proton linac (SPL), the PS2, and the upgraded SPS at CERN, as well as critical issues of the FAIR design. Here issues of electron cloud, space charge, beam impedance, the generation and the stability of future LHC beams in the PS and SPS, beam loss handling, and beam stability aspects for the FAIR rings were discussed. At BEAM’07 inter-laboratory collaborations could be reinforced and valuable experiences from several other facilities were presented, including superconducting linac operation and laser stripping at SNS, ESS R&D, long-range beam–beam effects at RHIC, and luminosity-levelling attempts at the Tevatron.
