Performance Evaluation of Developed GEM-based X-Ray Diagnostic System

Abstract: The volume of data acquired from Gas Electron Multiplier (GEM) detectors increases with emerging demands for soft X-ray measurement of hot plasma. In order to reach the expectations of the high-quality measurement, construction of high-throughput and low latency processing system is required. Overview and details of the current state-of-the-art of the developed system will be presented. The prepared solution consists of dedicated acquisition hardware, FPGA preprocessing and High Performance Computing devices u… Show more

“…Algorithms for different spectra generation based on raw data X-ray pulses were implemented in MATLAB as reference [10] and in low latency versions [7] on CPU and GPU devices. This solution was comprehensively tested in terms of hardware performance [9] and whole data path throughput and latency with CPU algorithms. Tests have proven bottlenecks:…”

“…The system overview and more details of software architecture and data path can be found in [3]. The calculations of throughput of different parts of the system and assessment of the maximal hardware performance are described in [7]. The system used for this studies is capable of processing 243902 events/second and 9.54 Gbit/s (approx.…”

“…In this mode, for each crossing of the signal above the trigger level, a set of 40 samples from all channels is gathered (such a set is called the event in the article). More details about this mode and its limitations are described in [7]. Another, local trigger mode is also implemented and tested [9,10].…”
