Summary: | In the high luminosity Large Hadron Collider upgrade of the A Toroidal LHC ApparatuS (ATLAS) experiment in 2026, the new inner tracker detector will be installed. As a promising candidate for the outer layer of the inner tracker detector, the High Voltage CMOS (HV-CMOS) pixel sensors are being investigated by the ATLAS collaboration. A Front-End LInk eXchange (FELIX) based Data Acquisition (DAQ) system is developed for the R&D of the HV-CMOS sensors. A FELIX card with a Peripheral Component Interconnect express interface in the back-end is used to control, monitor, calibrate, and read out the front-end electronics. In the front-end, a Xilinx evaluation board ZC706 works as the interface between the back-end and the custom boards with HV-CMOS sensors and the readout Application-Specific Integrated Circuit. The DAQ system was successfully deployed for the testbeam experiment at CERN. The design of the DAQ system, the tuning of sensors, and the testbeam results will be described in details. |
