The Accelerator on a Chip International Program (ACHIP): Status and Outlook — •Norbert Schönenberger, Johannes Illmer, Ang Li, Stefanie Kraus, Anna Mittelbach, Roy Shiloh, Alexander Tafel, Peyman Yousefi, Peter Hommelhoff, and The ACHIP Team — Department Physik, Friedrich-Alexander-Universität Erlangen-Nürnberg (FAU), 91058 Erlangen

Dielectric laser acceleration (DLA) is based on the interaction of pulsed electron beams and laser-excited near-fields at photonic structures. Resulting acceleration gradients have approached 1 GeV/m and thus make this technology a promising candidate for a small-footprint accelerator. ACHIP aims to demonstrate an electron accelerator with a shoebox-sized footprint and 1 MeV final beam energy. Here the status and outlook of this endeavour are summarized. The emphasis is on recent results showing velocity micro bunching of sub relativistic electrons and subsequent probing of the phase space via a second laser-electron interaction. Furthermore, challenges and developments related to the necessary high brightness cathodes, transverse and longitudinal sub-relativistic electron dynamics, on-chip photonics-based laser coupling and the integration of all components of the envisioned MeV accelerator are detailed.
