(a) Scheme of the devices mounted in front of the beam: 1 – camera with engraved YAG:Ce scintillator; 2 – microfluidic dosimetry cell; 3 – masked photodiode; 4 – manual micro-translation table (s-axis); 5 – AXMO translation table (x, z-axis). (b-i) Photograph of the scintillator with engraved axes and rectangle pattern to simulate the microfluidic window (see text for more details). (b-ii) Visualization of the synchrotron beam projected on the YAG target (in blue). The width of the monochromator exit slits was adjusted to 500 µm (z-axis), resulting in a beam almost similar to the vertical dimension of the cell window. (b-iii) Photograph of the brass mask applied on the photodiode: a rectangle 0.29 mm × 1.07 mm was drilled in the center with a precision of 20 µm.
