  abstract = {High-flux, high-energy 𝛾-ray measurements are constrained by pulse pile-up and detector saturation.<br />To address this issue, a well-type BGO scintillation detector based on a controlled low-efficiency sam-<br />pling strategy is proposed, enabling online measurement of high-flux 𝛾-ray beams. The design reduces<br />the probability of full-energy absorption while maintaining a stable detector response, allowing reliable<br />operation at elevated flux levels. The detector performance was systematically evaluated through Monte<br />Carlo simulations, energy calibration using (p,𝛾) reactions, and on-beam tests at SLEGS. The results show<br />that the detector operates stably over an energy range of 5.5–21.7 MeV at fluxes of approximately 10⁵ s⁻¹,<br />without performance degradation. The experimental results agree well with the simulated one over the<br />energy range, validating the reliability of both the model and the measured data. The detector provides an<br />effective and scalable solution for real-time monitoring of high-flux 𝛾-ray beams.},
