Abstract Laser plasma accelerators (LPAs) enable the generation of intense and short proton bunches on a micrometre scale, thus offering new experimental capabilities to research fields such as ultra-high dose rate radiobiology or material analysis. Being spectrally broadband, laser-accelerated allow for tailored volumetric deposition in sample via single excite probe specific properties. The rising number experiments indicates need diagnostics providing spatially resolved characterization distributions with volumes approximately 1 cm ${}^3$ fast online feedback. Here we present scintillator-based miniSCIDOM detector single-bunch tomographic reconstruction up . achieves spatial resolution below 500 $\unicode{x3bc}$ m sensitivity 100 mGy. performance is tested at therapy cyclotron an LPA source. experiments’ primary focus scintillator’s ionization quenching behaviour.
