ITER Diagnostics.

Overview of diagnostics on ITER neutral beam test facility

ITER operation relies on heating neutral beam injectors (HNB) based on negative ion deuterium beams accelerated at 1 MeV, with up to one hour 17 MW power, uniform intensity and low divergence. A neutral beam test facility is being built at Consorzio RFX to demonstrate the feasibility of a prototype injector with such demanding specifications and to optimize its performances. It comprises SPIDER...

Neutron Transport Analysis for In-vessel Diagnostics in ITER

Nuclear transport analysis using the MCNP code and heat analysis using a general purpose Finite Element Method code ANSYS 11, respectively, have been carried out for in-vessel components of the microfission chamber (MFC) and the poloidal polarimeter. The nuclear heating rates of the MI cable and the exhaust pipe of the MFC are highest in the gap between two adjacent blanket modules and decrease...

Progress in research and development of mirrors for ITER diagnostics

All optical and laser diagnostic systems in ITER will use metallic mirrors as plasma viewing elements. In the harsh environment of ITER, the performance of mirrors will decrease mainly because of erosion of their surfaces and deposition of impurities. The deterioration of optical properties of diagnostic mirrors will directly affect the entire performance of the respective ITER diagnostics, pos...
