International audience; We describe the performance of the Timepix silicon detector operation at the SPS and H8 extracted beam line at CERN. Some detector calibration results and tuning will be discussed and a new cluster analysis algorithm, to reconstruct the particle hits, is described as well. We investigated the optimal acquisition setup for the Timepix device in order to use its full capabilities. A setup of 4 planes of the Timepix hybrid silicon pixel detector is tested as a hodoscope in the H8 180 GeV/c extracted pion beam, and also with a special 3 ns channeled proton bunch sequence inside the SPS accelerator. Spatial and angular distributions are measured.
