The S-DALINAC at TU Darmstadt is a 3 GHz electron accelerator that allows the possibility to operate it in an energy recovery LINAC (ERL) mode. The multi-turn ERL operation mode was demonstrated in 2021. During the operation in this mode once accelerated and once decelerated beams share the same beamline which leads to the repetitive bunch rate of 6 GHz. A non-destructive beam monitoring tool is important for the simultaneous position measurement of both beams. For these purposes a setup based on Low Gain Avalanche Detectors (LGADs) is being developed for the beam time structure monitoring. LGADs are silicon detectors optimized for 4D-tracking with timing precision below 50 ps thanks to an internal charge amplification mechanism which makes it an ideal candidate for precise timing monitoring at S-DALINAC.
