High-Speed-PIXE is the term for fast spatial-resolved particle-induced X-ray emission.

Actually, a unique HS-PIXE-Set-up is developed at the HZDR ion beam centre by using high-energy protons from a 6 MV tandem accelerator as excitation radiation for spatial-resolved chemical analysis.

The spatial resolution is hereby not reached by scanning the sample, but by a CCD-Based X-ray camera(1) with spatial and energy resolution (pixel: 48 x 48 µm2). A similar set-up has yet been tested only at synchrotron facilities (Scharf et al., 2011). The use of such kind of a camera with protons as excitation source is unique on a world-wide scale.
