Abstract
Abstract Conceptual design and construction of the “TMA” tokamak is presented. TMA is a Tokamak of Minor Aspect ratio (A = 2) and elongated cross section k ≤ 2. It is planned to be created on the basis of existing TSP tokamak-complex at TRINITI, Troitsk, on a short time. Main parameters of installation are: toroidal field Bto≤2T, major plasma radius R = 0.7 m, minor plasma radius a = 0.35 m, plasma current Ip ≤ IMA, plasma elongation k ≤ 2, triangularity δ ≤ 0.7. Inductor flux of a value Δφ = ±0.5 V.s, plasma RF heating power PRF ≤ 9 MW. Duration of plateau of toroidal field is expected to be Δt = 2 s. Main goals of TMA are: study of moderate aspect ratio of elongated shaped plasma with divertor, achievement of a high bootstrap current, study of active controllable SOL plasma.
