Laser Thomson scattering (LTS) is a measurement technique that can determine electron velocity distribution functions in plasma systems. However, accurately inferring quantities of interest from an LTS signal requires the selection of a plasma physics submodel, and comprehensive uncertainty quantification (UQ) is needed to interpret the results. Automated model selection, parameter estimation, and UQ are particularly challenging for low-density, low-temperature, potentially non-Maxwellian plasmas like those created in space electric propulsion devices.

- Laser Thomson scattering (LTS) is a technique for measuring electron properties in plasma, especially across varying plasma regions like the presheath and sheath.
- Previous studies utilized laser diagnostics and electrostatic probes, but this work focuses on a specific setup designed for measurements along the electrode normal vector, crucial for validating sheath models.
- The research develops a discharge plasma cell that measures electron temperature and density in an argon plasma at different voltages, revealing key properties of the plasma and suggesting that the diagnostic step size could be improved for more precise results.
