Description
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 and time stamping with an accuracy of approximately 10 ns. Tests with particle beams are needed to assess the performance of existing and future prototype assemblies. To this end a high-resolution beam telescope based on Timepix3 hybrid pixel-detector assemblies with data-driven readout has been constructed and successfully commissioned in the H6 beam line of the CERN SPS. It allows for track reconstruction at high particle rates (data driven readout with up to 10 million tracks / second) and with excellent spatial (~2 microns) and temporal (~1 ns) resolution. The readout system follows the LHCb Timepix3 telescope architecture based on SPIDR boards and Xilinx Virtex-7 FPGAs. Several pixel detector prototypes with different readout architectures have been integrated into the telescope DAQ system and operated with high-energy hadron beams. The EUTelescope software framework is used for the reconstruction and data analysis. We present performance results for the telescope, discuss the event building and reconstruction methods for various devices under test and show examples of ongoing data analyses.
