How reliable are line intensities for temperature calculation using the Boltzmann plot method
Year: 2025
Type: article
Abstract: This study investigates the reliability of electron temperature calculations for plasmas using line intensities, specifically through the Boltzmann plot method. Simulated spectra of a copper plasma reveal that while using line intensities may be sufficient under certain conditions, significant deviations arise under high-pressure and low-temperature scenarios. Our findings emphasize the need for caution, as inaccuracies can occur when the optical depth reaches a relevant magnitude.
