  The Diamond storage ring has been upgraded to replace one cell of Double Bend Achromat (DBA) with a Double Double Bend Achromat (DDBA). This upgrade has enabled the construction of a new straight to install a much brighter insertion device X-ray source for a new beamline rather than use a weaker bending magnet source. The engineering challenges and experience from this project are described, especially those aspects relevant to building a future low emittance storage ring at Diamond.

  Failure of a superconducting cavity in the Diamond storage ring can lead to extended down-time because of the time required to remove the module from the ring, the inability to access the cavity without removal from the cryostat and the long time to repair of the module. To reduce the risk to storage ring operation, normal conducting cavities are being installed to support operation of the superconducting cavities. Two cavities will be introduced in 2017 and work is progressing with RF amplifiers, transmission lines and low-level RF as well as storage ring engineering and controls. A summary of progress so far is presented and the plan for installation and further RF upgrades is outlined.
