This paper presents the data acquisition system for GEM-detector (Sauli in Nucl Instrum Methods Phys Res Sect A Accel Spectrom Detect Assoc Equip 386(2–3): 531–534, 1997. https://doi.org/10.1016/S0168-9002(96)01172-2 ) based cameras and spectrometers (Chernyshova et al. Fusion Eng Des, 2017. https://doi.org/10.1016/j.fusengdes.2017.03.107 ). The is modular (Czarski Rev Sci 87(11): 11E336, 2016. https://doi.org/10.1063/1.4961559 supports 1D 2D GEM arrays with software-defined readout modes. Channel count can vary from 8 up to hundreds. electronics consists of two units—radiation tolerant Analog Front End rack-mount processing unit. Data split into parts—real-time hardware, on FPGA software, embedded multicore CPUs hardware accelerators. subsystem together PCIe interface multi-core Xeon processors forms low latency, high-performance chain suitable applications requiring feedback. detectors tokamaks operate high magnetic field, so was equipped multipoint field measurement synchronized detector readout. also includes custom HV supply, developed triple operating high-rate mode. Dedicated protection diagnostic subsystems were as well ensure safe reliable operation harsh conditions. To support high-temperature surrounding, liquid cooling (Wojenski J 11(11): C11035, 2016).
