Laser-driven plasma accelerators (LPA) are compact sources of ultra-short, intense proton pulses in the multi-10-MeV energy range. These unique parameters predestine LPAs as powerful tools for ultra-high dose rate radiobiology research. To promote further sophisticated radiobiological studies at LPAs, automated setups for proton acceleration and beamline operation are required.
In this contribution, we will present our concept for an automated, repetion rate-capable LPA setup for radiobiological applications, extrapolating from radiobiological studies performed at the ALBUS-2S beamline at Draco PW (HZDR). Our concept combines a cryogenic jet target as proton source, a 1-Hz pulsed solenoid beamline for spectral shaping of proton bunches and dedicated realtime source-to-sample diagnostics for the proton bunch. These tools will be combined to enable the irradiation of radiobiological samples in scanning mode, i.e. spot-wise irradiation, with an automated feedback loop between LPA source, beamline and irradiation pattern.
