The quantitative measurement evaluation of composition especially of high -intensity beams are limited and can become a challenge with conventional methods especially with simplified instrumentation for ease of deployment. For purpose, we developed a novel technique based on high -resolution spectral -sensitive tracking of single particles scattered from the beam path by a thin foil. We use a compact radiation camera equipped with the semiconductor pixel detector Timepix3 together with dedicated Monte -Carlo simulations. Particle -event type discrimination and directional information are produced by the detector spectral tracking response together with particle -type resolving power derived from experimental calibrations. Directional- and spectral -sensitive components can be resolved in wide field -of -view. Quantification of the primary beam intensity is extrapolated by numerical calculations. Demonstration and evaluation of the technique are provided by measurements with 33 MeV protons from a light ion cyclotron accelerator. Scattered particles originating from the thin foil, the accelerator beam nozzle, and air space along the beam path are detected and evaluated.
