Description
The recent installation of a new photocathode drive laser has significantly improved the reliability of photoinjector operations at the APS, Argonne. The photoinjector is designed to operate in two distinct modes: high-charge (Hi-Q) mode and high-brightness (Hi-B) mode. The Hi-Q mode is intended for direct injection from the linac into the booster ring to support APS-U operations, eliminating the need for charge accumulation typically performed in the particle-accumulator ring. In contrast, the Hi-B mode optimizes the photoemission source to produce high-brightness electron bunches with sub-micrometer emittance at 100 pC, which can be delivered to the Linac Extension Area (LEA) for advanced accelerator research and development.
In this paper, we present beam-dynamics modeling and optimization of the photoinjector beam for both Hi-Q and Hi-B modes. Additionally, we report the first experimental measurements of photoinjector beams generated using the new drive laser and compare these results with simulation predictions.
