  The ESRF is close to the end of the first phase (2009-2015) of its Upgrade Programme and has defined the objectives for the ensuing second phase. It envisions a major upgrade of the source to best serve the new science opportunities. The ESRF Council endorsed the proposal to perform the technical design study of a new 7-bend achromat lattice. This configuration will allow the storage ring to operate with a decrease in horizontal emittance by a factor of about 30 and a consequent increase in brilliance and coherence of the photon beam. This paper reports on the status of the accelerator project, highlighting the progress in the technical design.

  The proposed 7-bend achromat lattice for the new 6 GeV electron storage ring of the European Synchrotron Radiation Facility imposes a change of the entire vacuum system. Small bore magnets will require low conductance vacuum chambers. Conventional vacuum pumps will have to be assisted by distributed pumping provided by Non-Evaporable Getter (NEG) coating. The time constraints for design, prototyping, pre-assembly, installation and commissioning of the new systems require simple solutions and the use of existing expertise where possible. In this paper the draft layout of the vacuum system will be explained, information about the expected dynamic pressure distribution and conditioning will be given. Some technical solutions to resolve specific issues arising from the small vacuum chamber dimensions and the dense arrangement of components are described.
