Towards the Realization of a Dielectric Laser Accelerator Beamline: Staging and Transverse Dynamics — •Joshua McNeur, Martin Kozak, Norbert Schönenberger, Ang Li, Alex Tafel, and Peter Hommelhoff — Department Physik, Friedrich-Alexander-Universität Erlangen-Nürnberg (FAU), Staudtstr. 1, 91058 Erlangen

Dielectric laser accelerators (DLAs) belong to a novel regime of accelerators that aim to reduce both the cost and footprint of state-of-art Microwave Linacs. Their orders-of-magnitude smaller footprints and larger acceleration gradients potentially enable University-lab scale (and smaller) high energy electron sources with a wide range of applications, ranging from tumor irradiation to x-ray generation. However, to progress from the proof of principle DLA experiments [1,2] to a DLA-based accelerator beamline, many challenges need to be addressed. Here, we discuss experimental confirmation of DLA-based staging, deflection and focusing, crucial steps towards the realization of a DLA-beamline [3].
