Electromagnetic Analysis Of The Iter H-Alpha Diagnostic Components

The H-alpha diagnostic components are attached to the ITER equatorial port-plug (EPP) #11. Diagnostic system includes four mirrors, shutter unit with driven shaft and built-in mirror cleaning system (MCS). Modified finite element model created with the Ansys Maxwell software was used to obtain electromagnetic (EM) forces for the updated design of H-alpha diagnostic components during plasma disruption. This EM model contains important surrounding structural elements of the equatorial port, such as the updated DSM 02 in the equatorial port #11, which includes backfillings (surrounding structures of the H-alpha components) and trays.
