Synergistic Suppression of Secondary Electron Yield from Al₂O₃ Ceramic Windows by TiN Film and Laser Surface Texturing [PDF]

Nanomaterials
To suppress the Secondary Electron Yield (SEY) of Al2O3 ceramic surfaces for accelerator ceramic windows, a synergistic strategy integrating TiN film deposition and laser surface texturing was developed. TiN films were first deposited on Al2O3 substrates

Covariance of resonance parameters ascribed to systematic uncertainties in experiments [PDF]

EPJ Web of Conferences, 2023
In resonance analyses, experimental uncertainties affect the accuracy of resonance parameters. The resonance analysis code REFIT can consider the statistical uncertainty of the experimental data when evaluating the resonance parameter uncertainty ...

Effect of sample density in prompt γ-ray analysis

Scientific Reports, 2022
A high-accuracy analytical method is broadly required to obtain reliable research results. Thus, prompt γ-ray analysis (PGA), one of the most accurate non-destructive analytical methods, has been employed in various fields.
