Abstract	The UK-XFEL spreader will distribute 1 MHz bunches between ten undulator beamlines. Each of the different paths through the spreader must transport an electron bunch to the undulator with minimal increase in the emittance and energy spread, whilst also conforming to various geometry constraints. To minimise the energy spread/emittance growth, the design was optimised to mitigate the effect of coherent synchrotron radiation (CSR). This was done by control of the phase advance between repeated sections, and by cancelling CSR kicks using a single kick CSR model. Due to the number of constraints that needed to be adhered to, an optimisation tool was developed to aid in the design of the optics. This paper will give an overview of the optimisation tool, show the design of different sections of the spreader, and then show the results of beam tracking.
