      abstract     = {During 2022 data taking (Run III) PADME searched for a
                      resonant production and a visible decay of the X17 particle
                      into e$^{+}$e$^{-}$. A precise knowledge within 1\%
                      uncertainty of the number of positrons was required for the
                      observation. To that purpose, an array of 2 × 6 Timepix3
                      (total of 512 × 1536 pixels) hybrid pixel detectors
                      operated in data-streaming mode with ToA resolution of 1.56
                      ns for every pixel was employed. Two methods for data
                      acquisition were developed. A frame-based method,
                      integrating the number of hits for each individual pixel for
                      a predefined period of time served for monitoring the beam
                      conditions and to provide a rough estimation of the beam
                      distribution and number of positrons. A data streaming mode
                      exploiting the nanosecond time resolution of Timepix3
                      detector was used for precise characterization of the
                      transverse beam profile and the distribution of the incident
                      positrons within each bunch of ∼ 200 ns duration.},
