SparkPix-RT

SparkPix-RT2

The SparkPix-RT project aims to develop next-generation intelligent X-ray detectors and co-designed AI/ML architectures for real-time data processing, enabling autonomous experiments and ultra-high-resolution imaging at next-gen light sources like LCLS-II and APS-U.

Key Objectives

  • Co-design multi-tiered hardware/software pipelines with real-time feedback for autonomous experiments.
  • Design advanced X-ray detectors with picosecond timing, MHz/GHz frame rates, and expanded sensitivity for ultrafast science.
  • Integrate FPGA-based edge computing and ML/AI workflows for dynamic data extraction and compression during experiments.
  • Optimize sensor and ASIC technologies for high dynamic range, resolution, and efficiency across energy ranges.
