Description
The Argonne Wakefield Accelerator's main beamline -- the drive-beam beamline -- utilizes a $1 +\frac{1}{2}$-cell radiofrequency photoinjector at 1.3 GHz to produce high-charge bunches. This contribution discusses an experiment to investigate photoemission from the RF gun over a wide range of operation parameters spanning different emission regimes. It especially demonstrates the generation of a $>50$-nC bunches using a $\sim 300$-fs UV laser pulse corresponding to an initial multi-kA peak current. The measurements are compared with numerical simulations performed with the ASTRA beam dynamics program. The transport and further acceleration of these bunches are investigated via numerical simulations.
