Detector electronics sub-system development for the NewAthena Wide Field Imager

Original language description

The Wide Field Imager (WFI) is one of the two instruments of the NewAthena X-ray mission selected by ESA. Five DEPFET detector modules are implemented in WFI that detect energy, spatial distribution and incidence time of incoming X-ray photons within the energy range of 0.2 keV up to 15 keV. The WFI instrument successfully completed the Instrument System Requirement Review (I-SRR) in March 2022. NewAthena had undergone a mission redefinition, and on February 2024 the mission restarted again. On the road to NewAthena launch, an Engineering Model (EM) as well as a Structural and Thermal Model (STM) of the WFI Detector Electronics Sub-System (DES) is developed. In this paper we present the current status of the DES development. Each DES consists of three modules: Galvanic Isolation Module (GIM), Power Conditioning Module (PCM) and Frame Processing Module (FPM). The function of the FPM is to control the readout Front End Electronic ASICs of its corresponding detector module. The FPM digitizes the analog output signals of the CH and performs an on-board preprocessing. The preprocessing and the control signal generation is done by the FPGA-based Frame Processor (FP). The GIM provides the primary to secondary power conversion, generating all the low voltages required for the operation of the DES, as well as the back- contact high-voltage (up to200 V) required for the detector operation. It is composed of custom-designed DC-DC converters. Another task of the DES is to provide all the regulated power lines to the CH. More than twenty independent power lines are supplied from the DES to the detectors and have to be switched on and off in a specified sequence. This function is implemented within the PCM.
