PINEM, the exchange of photons with a given electron, could be regarded as the fundamental effect governing DLA in the quantum regime. Understanding PINEM physics is an excellent approach to thinking about more efficient DLA structures. I will discuss the link between PINEM and DLA in detail, towards higher-gradient acceleration
The experimental complexity of DLA experiments increases with increasing structure length and the utilization of more complex laser pulse shapes, such as pulse front tilts. Consequently, the experiments involve many parameters demanding careful control and optimization. Previous studies have demonstrated the efficacy of machine learning (ML) in enhancing the performance of conventional...
We present our results for the design, fabrication, and testing of silicon-based, sub-relativistic Dielectric Laser Accelerators (DLAs) which use optical near fields to accelerate and confine electrons over extended distances. We describe how Alternating Phase Focusing (APF) lattices are incorporated to longitudinally/transversely focus/defocus electrons in an alternating fashion based on...
In this talk the DLA-related experiments at the SINBAD/ARES linear accelerator at DESY are presented. Both recent results, as well as future plans are discussed.
In the first part of the talk I will briefly review the literature on Smith–Purcell Free Electron Lasers, and speculate about the possibility of scaling down a radio wave amplifier: coupled-cavity Travelling Wave Tube, to obtain a light-generating device based on nanostructures. In the second part of the talk I will show concrete numerical results on Cherenkov Diffraction Radiation: the...
