Abstract In 2021 JET exploited its unique capabilities to operate with T and D–T fuel an ITER-like Be/W wall (JET-ILW). This second major campaign (DTE2), after DTE1 in 1997, represented the culmination of a series enhancements—new fusion diagnostics, new injection capabilities, refurbishment plant, increased auxiliary heating, in-vessel calibration 14 MeV neutron yield monitors—as well as significant advances plasma theory modelling community. DTE2 was complemented by sequence isotope...
Laser Induced Breakdown Spectroscopy (LIBS) method is considered to be a promising tool for analyzing the retention of hydrogen isotopes (D and T) helium (He) on first walls divertor regions future fusion reactors. Helium will produced in DT reactions but could also used initial non-nuclear phases DEMO concepts. The present study investigates He detection by LIBS Be coatings simulating deposits plasma-facing components JET while results are relevant other wall materials. was carried out...
Understanding the interaction between fusion plasma and plasma-facing materials (PFMs) is crucial for achieving optimal performance, safety, lifetime of devices. Relevant have been intensely studied to determine fuel retention composition co-deposited layers on PFMs by depth profile analysis using Laser-Induced Breakdown Spectroscopy (LIBS) Calibration-Free (CF)-LIBS. However, comparison containing a mixture different (seeding) gases LIBS, has not systematically. Consequently, aim this work...
Controlling plasma fuel retained in the facing components of first wall a fusion reactor is one most important challenges influencing safe operation International Thermonuclear Experimental Reactor place. This issue proposed to be addressed by laser-induced breakdown spectroscopy (LIBS) diagnostics, which particularly powerful studying near-surface deposits and analyzing their composition. The main goal present study determining depth profiles different elements beryllium-based materials...
