  The design and optimisation of the new DDBA lattice for Diamond has been performed taking fully into account, from the early stages, the geometry and the engineering integration constraints. In this paper we review the evolution of the DDBA cell, the rationale for its modification and the optimisation strategy used.

  The project to install a Double Double Bend Achromat (DDBA) providing an additional Insertion Device (ID) source for a new beamline at the Diamond Light Source is proceeding. This DDBA cell employs many of the technologies required for Diffraction Limited Storage Rings (DLSRs) and this paper describes the vacuum vessel, magnet and girder solutions in manufacture for the DDBA.

  The concept of converting individual cells of the Diamond Double Bend Achromat (DBA) lattice into a modified 4-bend achromat with a new straight section for insertion devices (IDs) in the middle of the arc, grew out of earlier studies of low emittance MBA lattices*, and was motivated by the need for additional ID straight sections, since all of the 22 ID straight sections in the Diamond storage ring are either occupied or have been allocated to future beamlines. Such a modification effectively replaces each DBA cell with two new DBA cells, hence the term Double-DBA or DDBA has come to be used for the project. Since the tangent point for bending magnet beamlines lies close to the start of the second dipole in the original DBA, this allows unused exit ports and spaces on the experimental hall which are available for future bending magnet beamlines to be used for higher performance ID beamlines. In this report we present an overview of the status of the project, the various accelerator physics and engineering studies that have been carried out, and plans for the implementation of one or two DDBA cells in Diamond.
