Sumario:For future upgrades of the LHC it is necessary to develop new tracking detectors: more radiation hard and cost efficient pixel detectors with high spacial resolution are required for the planned high luminosity version of the LHC (HL-LHC). For future tracking devices HV-CMOS active pixel sensors are great candidates since they fulfill all the demands mentioned above. First prototypes of these sensors are assembled on custom test boards and together with FE-I4 readout chips they make up the first test pixel detectors. One approach for testing these chips is through using lasers to induce electron-hole-pairs into the depletion zone of the sensor chip diodes to simulate an ionizing particle crossing through the bulk. Comparison measurements of irradiated/non-irradiated sensors are used to explore the radiation hardness of the sensors.
