The vertex- and tracking detectors at the proposed high-energy CLIC electron-positron collider will be based on small-pitch silicon pixel- or strip detectors. The requirements for these detectors include single-point position resolutions of a few microns combined with nanosecond time tagging of hits. Tests with particle beams are needed to assess the performance of existing and future prototype assemblies. To this end the CLIC detector and physics collaboration (CLICdp) operates a high-resolution beam telescope in the H6 beam line of the CERN SPS. It is based on Timepix3 hybrid pixel-detector assemblies with data-driven readout, allowing for track reconstruction at high particle rates (up to 10 million tracks / second) and with excellent spatial (<~2 microns) and temporal (<~1 ns) resolution. Several pixel detector prototypes with different readout architectures have been integrated into the telescope DAQ system and operated with high-energy hadron beams. We discuss performance results for the CLICdp reference telescope, the event building and reconstruction methods for various devices under test and show examples of ongoing data analyses.
