S. Almaviva

About

S. Almaviva is a leading researcher in the field of nuclear fusion diagnostics, with a primary focus on Laser-Induced Breakdown Spectroscopy (LIBS) for in-vessel tritium retention analysis. Their work centers on developing remote LIBS systems to measure hydrogen isotopes—particularly deuterium as a proxy for radioactive tritium—on plasma-facing components inside fusion reactors like the FTU (Frascati Tokamak Upgrade). Almaviva's major contributions include pioneering the integration of LIBS with robotic arms for autonomous, in-situ measurements inside vacuum vessels, a critical advancement for fusion safety and fuel cycle management. Their 2020 paper on LIBS measurements inside the FTU vessel mock-up using a robotic arm has garnered 49 citations, while their 2019 study on deuterium detection in the FTU toroidal limiter (40 citations) demonstrated the technique's viability for quantifying retained fuel on molybdenum (TZM) tiles. These achievements, complemented by accessory laboratory studies (13 citations), have established Almaviva as a key figure in developing real-time, non-destructive diagnostics for next-generation fusion devices like ITER, enabling safer and more efficient tritium management.
