abstract = {{The Advanced Light Source Upgrade (ALS-U) is an ongoing upgrade of the ALS facility at Lawrence Berkeley National Laboratory. The project utilizes an on-axis swap-out injection between a new Storage Ring (SR) and a full-energy Accumulator Ring (AR) to enable small dynamic apertures to deliver higher brightness. The ALS-U injection scheme plans to use a pulsed stripline kicker design based off of a successful research and development kicker that was installed on the existing ALS Storage Ring. A key challenge in the ALS-U Swap-out kicker is optimizing the distance between the electrodes to balance the benefits of tight spacing to lower required pulser voltage and the challenges to the mechanical design that comes from higher electrode thermal expansion due to increased synchrotron and beam induced heating. Structural and thermal analysis shows that adapting high emissivity coatings, an accommodating mechanical supports design and using molybdenum as an electrode material provide a robust solution.}},
