Fluorescent-target imaging and real-time beam diagnostics at the High Energy Photon Source.
Article in Journal of synchrotron radiation, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Fourth-generation synchrotron radiation sources based on diffraction-limited storage rings impose stringent requirements on beamline alignment precision, diagnostic reliability, and real-time monitoring under high-brightness operating conditions. To address these requirements, an integrated fluorescent-target imaging and real-time beam diagnostic platform has been developed at the High Energy Photon Source (HEPS). The system incorporates a radiation-tolerant and ultra-high-vacuum-compatible mechanical assembly with diamond and YAG:Ce scintillators for different heat-load conditions. A distributed multi-camera architecture implemented within the Experimental Physics and Industrial Control System (EPICS) areaDetector framework enables synchronized multi-angle monitoring of beam profiles. Key beam parameters are extracted through online image processing and published as EPICS process variables for control-system integration. To support high-throughput diagnostic data handling, the platform further integrates the Mamba Data Worker framework, enabling coordinated multi-target acquisition, HDF5 storage, and automated metadata ingestion into a dedicated HEPS beamline alignment database. Representative deployment demonstrated stable synchronized operation of 13 cameras, with online analysis completed in less than 20 ms and end-to-end latency below 50 ms. These results establish a practical and scalable framework for beamline diagnostics, alignment support, and data-driven optimization at HEPS.
