Development of detectors suitable for identification and characterization of laser accelerated ion bunches is of great importance, both for understanding the acceleration processes and subsequent applications. Our dedicated aim is to develop and implement online solutions for spatially and energy-resolved ion distribution measurements. Those must work reliably during the interaction of the high power laser pulse with the target. This poses a remarkable challenge, for example due to the tremendous electromagnetic pulse (EMP) that is generated. Our approaches cover a wide range of physical processes that are triggered upon the interaction of ionising radiation with matter. Amongst the intriguing detection mechanisms is the excitation of sound waves.
