Abstract

The accelerator R&D facility SINBAD (Short innovative bunches and accelerators at DESY) will drive multiple independent experiments, including the acceleration of ultrashort electron bunches and the testing of advanced high-gradient acceleration concepts. The SINBAD-ARES (Accelerator Research Experiment at SINBAD) setup hosts a normal conducting RF photoinjector generating a low-charge electron beam, which is afterwards accelerated by an S-band linac section. The linac as well as a magnetic chicane will allow the production of ultrashort bunches with excellent arrival-time stability. The high brightness beam has then the potential to serve as a test beam for next-generation compact acceleration schemes. The setup of the SINBAD-ARES facility will proceed in stages. We report on the current status of the ARES RF gun commissioning and linac setup.

Summary

Introduction

SINBAD [1] is a dedicated R&D facility in the former DORIS tunnel at DESY Hamburg. The goal is to test advanced acceleration techniques, such as Laser driven plasma Wake-Field Acceleration (LWFA), Dielectric Laser Acceleration (DLA) and THz-driven acceleration, in independent experiments. ARES [2] at SINBAD is a linear accelerator with a target energy of 100-155 MeV which is currently in the construction and commissioning phase. The facility will provide a low-charge, remarkably short-bunch electron probe beam with excellent arrival-time stability [3]. Emittance (rms) [μm rad] Bunch length (rms) [fs] Arrival time jitter [fs]. The following section provides an overview of the ARES layout and the current status of the accelerator installation as well as the RF gun conditioning.
