Soft X-ray (SXR) plasma measurements are important type of diagnostics especially in tokamak facilities. Main output products are energy and topology spectra distributed in time. In case of Gas Electron Multiplier (GEM) detectors, used as radiation sensors, large number of analog readout channels must be provided. For this purpose Field-Programmable Gate Arrays (FPGAs) are used. Data quality monitoring (DQM) is important topic in case of asynchronous events registered by the measurement unit. Due to numerous FPGAs used it is necessary to provide advanced trigger synchronization between them. In the paper is proposed an algorithmic approach for the trigger link training and diagnostics. It is a key component in order to provide consistent measurement data for DQM analysis. The contents of the article covers the plasma experiments and related DQM topics. In following chapters explanation of the synchronization problem is described. The proposed algorithm will be used for trigger link synchronization and diagnostics aspects. The simulations are also discussed. Currently, the proposed ideas are at the stage of implementation and tests on real hardware. Simulation were successfully performed. Summary of the work carried out is presented at the end of the paper.

Based on the publications regarding new or recent measurement systems for the tokamak plasma experiments, it can be found that the monitoring and quality validation of input signals for the computation stage is done in different, often simple, ways. In the paper is described the unique approach to implement the novel evaluation and data quality monitoring (EDQM) model for use in various measurement systems. The adaptation of the model is made for the GEM-based soft X-ray measurement system FPGA-based. The EDQM elements has been connected to the base firmware using PCI-E DMA real-time data streaming with minimal modification. As additional storage, on-board DDR3 memory has been used. Description of implemented elements is provided, along with designed data processing tools and advanced simulation environment based on Questa software.

The validation of the measurements quality after on-site diagnostic system installation is necessary in order to provide reliable data and output results. This topic is often neglected or not discussed in detail regarding measurement systems. In the paper recently installed system for soft X-ray measurements is described in introduction. The system is based on multichannel GEM detector and the data is collected and sent in special format to PC unit for further postprocessing. The unique feature of the system is the ability to compute final data based on raw data only. The raw data is selected upon algorithms by FPGA units. The FPGAs are connected to the analog frontend of the system and able to register all of the signals and collect the useful data. The interface used for data streaming is PCIe Gen2 x4 for each FPGA, therefore high throughput of the system is ensured. The paper then discusses the properties of the installation environment of the system and basic functionality mode. New features are described, both in theoretical and practical approach. New modes correspond to the data quality monitoring features implemented for the system, that provide extra information to the postprocessing stage and final algorithms. In the article is described also additional mode to perform hardware simulation of signals in a tokamak-like environment using FPGAs. The summary describes the implemented features of the data quality monitoring features and additional modes of the system.

In scientific research, precise control of high voltages is crucial, particularly in ion traps and Gas Electron Multiplier (GEM) de tectors. The Sinara open hardware project addresses this need by developing a dedicated high-voltage system. The project introduces an STM32-based DIOT system board and a High Voltage Supply Board (HVSUP_ISOL) designed for non-real-time applications, providing up to +/-6kV. The HVSUP_ISOL board is fully isolated, ensuring system safety, and offers dual-channel configuration with a shared common terminal for easy casca ding. The firmware based on the MQTT protocol enables users to remotely control various settings, and telemetry data provi des insights into the system’s operation.
