Abstract
A toroidally viewing soft x-rayimaging system and an orthogonal matrix array of soft x-ray diodes are designed for identification of the small-scale plasma perturbations in the T-10 tokamak.Numerical modeling of the helical perturbations with high longitudinal wave numbers (m=5–30) is used for specification of the basic design of the system (optimal position of the diagnostic, field of view, and spatial and mode resolutions) in the T-10 tokamak. A system of external windings is designed for controllable excitation of the low-mmagnetic islands and for studies of their effect on small-scale modes.Keywords
