TI - Optimising the Diamond DDBA Upgrade Lattice for Low Alpha Operation J2 - Proc. of IPAC2015, Richmond, VA, USA, May 3-8, 2015 C1 - Richmond, VA, USA T2 - International Particle Accelerator Conference T3 - 6 LA - english AB - The Diamond storage ring will be upgraded during 2016 by replacing one of the existing double bend achromat (DBA) cells with a double-DBA (DDBA) cell*. One requirement of the upgrade is that following the installation of the new cell, Diamond should continue to offer dedicated user time in ‘low alpha’ mode**. In this paper we describe the particular challenges relating to this task, and present the lattice design and optimisation studies undertaken so far. The paper concludes by discussing preliminary studies of adding a second DDBA cell into the storage ring.
