Article Synopsis
- Helium diffusion and bubble dynamics are modeled using the finite element method, refining previous models to simplify calculations and improve efficiency.
- A parametric study explores how temperature (from 120 K to 1200 K) and helium flux impact bubble density, size, and overall helium inventory in the material.
- Results show that bubble size increases over time following a power law, bubble density peaks at a certain level, and the model's predictions align well with experimental data.
The efficient and reliable control and monitoring of the quality of the optical properties of mirrors is an open problem in laboratory plasmas. Until now, the measurement of the reflectance of the first mirrors was based on the methods that require additional light calibration sources. We propose a new technique based on the ratio of the red- and blue-shifted emission signals of the reflected hydrogen atoms which enables the in situ measurement of the spectral reflectance of metallic mirrors in low-density Ar-H or Ar-D plasmas.
