High-altitude intense pulsed $\gamma$-rays propagate through the upper atmosphere to generate intense radiation fields, which can lead to performance degradation or functional failure of electronic systems in orbiting spacecraft. By employing the Monte Carlo method combined with variance reduction t…
As the core guarantee for the performance of large-scale scientific facilities, particle accelerator alignment technology aims to achieve high-precision spatial positioning of critical components such as magnets. The leap in alignment precision from sub-millimeter to sub-micron and even nanometer le…
To calculate the detection efficiency curve and coincidence correction factors for a well-type HPGe detector, the detection efficiency of the HPGe was calibrated using commonly employed single-energy γ radionuclide standard sources, while cascade coincidence correction factors for common radionuclid…
Shanghai Proton Therapy Device (SAPT) represents the first domestically-developed proton therapy demonstration system. The rotating gantry constitutes a critical component of the proton therapy apparatus, achieving an isocentric accuracy of ±0.275 mm that surpasses international mainstream equipment…
To calculate the detection efficiency curve and coincidence correction factors for well-type HPGe, the detection efficiency of HPGe was calibrated using commonly employed monoenergetic γ-ray nuclide standard sources, while simultaneously measuring the cascade coincidence correction factors for commo…
The Shanghai Proton Therapy Device (SAPT) is the first domestic proton therapy demonstration system. The rotating gantry constitutes a critical component of the proton therapy apparatus, achieving an isocentric accuracy of ±0.275 mm that surpasses international mainstream equipment, thereby requirin…
Pre-oxidation is a critical step in the preparation of polyacrylonitrile-based (PAN) carbon fibers, and gamma irradiation represents an effective approach for optimizing the thermal pre-oxidation process. However, the effects and underlying mechanisms of gamma irradiation and thermal treatment seque…
Precise measurements of the cavity forward (Vf) and reflected signals (Vr) are essential for characterizing other key parameters such as the cavity detuning and forward power. In practice, it is challenging to measure Vf and Vr precisely because of crosstalk between the forward and reflected channel…
