Fusion energy is one of the most ambitious scientific frontiers, with the potential to provide an abundant, sustainable, safe, and environmentally considerate energy source. Unlike nuclear fission, fusion produces minimal greenhouse gas emissions and radioactive waste. However, achieving sustained fusion requires strict control over fuel source purity and stability, making quantitative high resolution mass separation of isotopes an essential analysis capability. Experimental reactors, like tokamaks, stellarators, and inertial confinement fusion (ICF) systems, operate under extreme conditions, where even trace impurities in hydrogen fuel can impact performance. Real-time analysis of hydrogen isotopes, helium byproducts, and light gases is crucial for optimising reactions and ensuring plasma integrity.
