Technical Design Considerations About the SINBAD-ARES Linac

The SINBAD facility (Short and INnovative Bunches and Accelerators at Desy) is foreseen to host various experiments in the field of production of ultra-short electron bunches and novel high gradient acceleration techniques. The SINBAD linac, also called ARES (Accelerator Research experiment at SINBAD), will be a conventional S-band linear RF accelerator allowing the production of low charge (0.5pC few pC) ultra-short electron bunches (FWHM, length <= 1fs few fs) with 100 MeV energy. In this paper we present the current status of the technical design considerations, motivate the foreseen diagnostics for the RF gun commissioning and present examples of foreseen applications.
