"The physics goals and operating conditions at existing and proposed high-energy\r\ncolliders, such as the Compact Linear Collider (CLIC), pose challenging demands on\r\nthe performance of their detector systems. Precise hit-time tagging, excellent spatial\r\nresolution, and low mass are required for the vertex and tracking detectors. To meet\r\nthese requirements, an all-silicon vertex and tracking detector system is foreseen for\r\nCLIC.\r\nThe ATLASpix high-voltage monolithic active pixel sensor (HV-MAPS) proto-\r\ntype was designed to demonstrate the suitability of the technology for the ATLAS\r\nInner Tracker Upgrade and the CLIC tracking detector. It is manufactured in the\r\nAMS aH18 process with a pixel pitch of 130 × 40 μm² and an active area of 3.25 ×\r\n16.0 mm².\r\nIn this thesis, the performance of the ATLASpix_Simple prototype is charac-\r\nterised in laboratory and test-beam measurements and evaluated with respect to\r\nthe requirements for the CLIC tracking detector. Samples with different substrate\r\nresistivities are compared.\r\nThe breakdown behaviour is determined, and a charge calibration of the thresh-\r\nold and the time-over-threshold charge is performed. A threshold dispersion of\r\n∼ 100 e-, a pixel noise of ∼ 120 e-, and a signal-to-noise ratio of ≥ 12 are measured\r\nusing an Fe-55 signal source. The power consumption of the sensor amounts to\r\n∼ 190 mW with the used settings.\r\nThe spatial resolution is close to the binary resolution limited by the pixel pitch,\r\nand the time resolution is found to depend significantly on the substrate resistivity.\r\nFor a 200 Ωcm sample, a time resolution of 6.8 ns after offline corrections is mea-\r\nsured at a detection threshold of ∼ 590 e-. High efficiencies well above 99.9 % are\r\nreached at low noise rates below 1 Hz on the full chip with a 200 Ωcm sample at a\r\nbias voltage of − 75 V and a threshold of ∼ 670 e-. Lower substrate resistivities show\r\na significantly worse timing performance and a smaller efficient operating window.\r\nFor a substrate resistivity of 200 Ωcm, an active depth of 55-61 μm is estimated at\r\na bias voltage of − 90 V.\r\nThe ATLASpix_Simple fulfils most of the requirements of the CLIC tracker. More-\r\nover, its successful operation has lead to the development of further HV-MAPS pro-\r\ntotypes, which are expected to meet all requirements and are currently investigated."^^ .
