Diagnostics for magnetic confinement fusion research

摘要: Significant progress towards the development of an attractive fusion energy source based on magnetic or inertial plasma confinement has been achieved within international program. High-level diagnostics capabilities are required to characterize plasmas and achieve a sound physics basis design power plant. A large variety different measuring techniques is used, most them detection electromagnetic radiation in wide range wavelengths particles emitted from plasma. Active probing by laser particle beams permits measure local parameters directly, whereas passive measurements imaging methods require unfolding tomographic reconstruction order obtain spatial distribution. Most systems limited accessible parameter range, accuracy, temporal resolution, resolution hardiness harsh environment, so that redundancy complementarity desirable. considerable synergy exists between for astrophysics research. In particular, novel detectors developed observation astrophysical objects may be applied devices, too. An overview requirements, selected results presented with emphasis toroidal devices.
