Numerical and experimental investigations of a microwave interferometer for the negative ion source SPIDER
R. Agnello, R. Cavazzana, I. Furno +4
The electron density close to the extraction grids and the co-extracted electrons represent a crucial issue when operating negative ion sources for fusion reactors. An excessive el…
Measure of negative ion density in a large negative ion source using Langmuir probes
Carlo Poggi, Monica Spolaore, Marco Barbisan +7
Neutral Beam Injectors (NBIs) based on negative ions are the workhorses of future fusion reactors, such as ITER, which they are expected to provide with up to \SI{33}{MW} of power…
