Functional model of the measuring head for the plasma fusion reactor wall diagnostics using low pressure, laser induced breakdown setup at random positions

Plasma Facing Components (PFC) diagnostics in fusion reactors require innovative and robust instrumentation capable of addressing the challenges of harsh operational environments. Hence, this work presents the design, construction, and testing of a functional model for a LIBS measuring head tailored for in-situ and post-mortem PFC analysis. The proposed system includes advancements in mechanical design, such as an adaptable measuring head configurations, which enable operation in low-pressure environments and random spatial positions within the reactor. By integrating spectroscopic techniques and remote control capabilities, the system demonstrates potential for real-time diagnostics with sensitivity comparable to state-of-the-art techniques.
