An electron cyclotron emission (ECE) receiver inside the electron cyclotron resonance heating (ECRH) transmission line has been brought into operation. The ECE is extracted by placing a quartz plate acting as a Fabry-Perot interferometer under an angle inside the electron cyclotron wave (ECW) beam. ECE measurements are obtained during high power ECRH(More)
A neutronics analysis has been conducted to investigate the streaming effect of fast neutrons in the waveguide channels of the ITER upper port ECRH launcher with the objective to assess the radiation loads to the beam windows. A suitable computational approach based on the Monte Carlo technique has been established to enable proper 3D calculations for the(More)
The objective of linear IFMIF prototype accelerator is to demonstrate 125 mA/CW deuterium ion beam acceleration up to 9 MeV. The injector has been developed in CEA Saclay and already demonstrated 140 mA/100 keV deuterium beam [R. Gobin et al., Rev. Sci. Instrum. 85, 02A918 (2014)]. The injector was disassembled and delivered to the International Fusion(More)
