2026-07-07 A THGEM-based Side-on Transition Radiation Detector for HERD: Engineering Prototype doi:10.57760/sciencedb.j00186.01142 en This dataset contains the raw detector data of the engineering prototype of a THGEM-based side-on transition radiation detector (TRD), along with the data that have undergone preliminary ROOT-based processing. The dataset is primarily used to evaluate the basic performance of the detector, including energy calibration, gain stability, and long-term operational stability.The dataset includes the following components:(1) 59 keV X-ray energy spectrum data: Raw data acquired under laboratory conditions using a tungsten-anode X-ray tube with a collimator. The dataset includes measurements taken with the X-ray tube both on and off to enable cosmic-ray background subtraction, and is used for detector energy calibration and gain calculation.(2) Gain stability test data: Raw data from gain stability tests performed at different incident rates (50, 100, 200, 300, 400, and 500 Hz), with both long-duration measurements (120 minutes per run) and short-duration cyclic tests (85-minute cycles). These data are used to evaluate the charging-up effects of the THGEM and the gain evolution over time.(3) Long-term stability monitoring data: Gain monitoring data sampled at irregular intervals over several weeks under fixed voltage and temperature conditions.All raw data have undergone preliminary ROOT-based processing, including baseline correction, signal extraction, and basic spectrum generation. The data are stored in ROOT file format, containing event-level and channel-level information on energy deposition, hit position, and other relevant parameters.It should be noted that the beam test data acquired at the CERN PS beam line are currently still under physical analysis and have not yet been fully processed. Therefore, the final analysis results from the beam test are not included in this submission. The related data will be released separately upon completion of the analysis.
