In tokamaks with tungsten-based plasma facing components, such as ITER, pollution of the plasma by heavy impurities is a major concern as it can lead to radiative breakdown. The radiation emitted by such impurities is mainly composed of x-rays in the

In ITER, reflection of photons on vacuum vessel will make parasitic signals (stray light) for optical diagnostics. In this study, to estimate and mitigate the effect of the stray light in ITER in a systematic manner, a ray transfer matrix was constru

ITER will be the first fusion device able to maintain fusion for long periods of time and therefore suitable to test integrated technologies, materials, and physics regimes necessary for the commercial production of fusion-based electricity. Therefor

Laser-induced fluorescence diagnostics on ITER will be used for local measurements of helium density (nHeI) and ion temperature (Ti) in the divertor area. The diagnostics is combined with divertor Thomson scattering via common laser injection and sig

ITER vertical neutron camera (VNC) is intended to measure time- and space-resolved neutron emission profile in the poloidal plasma section. It is composed of two fan-shaped collimating structures: lower (5 collimators) and upper (6 collimators). Ever

For a long time, nuclear fusion has been anticipated to become a future power source. The International Thermonuclear Experimental Reactor (ITER) tokamak is designed to demonstrate the feasibility of applying the deuterium-tritium fusion reaction to
