Following the successful demonstration of machine learning (ML) models for laser induced breakdown spectroscopy (LIBS) adaptation in fusion reactor fuel retention monitoring using synthetic data [Gąsior et al., Spectrochim. Acta, Part B 199, 106576 (2023)], this study focuses on implementing operability experimental data. To achieve this, Simulated Eperimental Spectra (SES) are generated and used validation a chemical composition estimation model trained dimensionally reduced spectral...
Retention of hydrogen isotopes in thermonuclear reactors is a safety and maintenance issue, thus requires contactless measurement method its level. Although calibration free LIBS proved usefulness on calibrated samples even tokamaks, performance may be deteriorated next-step fusion devices because sensitivity the plasma parameters as electron temperature density which are more challenging to precisely measured than laboratory conditions. Moreover, both Beryllium Tungsten have spectral lines...
