The tokamak TSP-AST concept

Design, simulation and construction of the Taban tokamak

“…The required high peak voltage and power to initiate the plasma discharge are obtained by the OH coil as an inductive energy storage element and the OH coils are poloidally distributed to maintain B OH =0 within the plasma volume. The 2D FEM simulation has been performed to position the coils [24,27,28]. The system has been designed for a maximum stray magnetic field of 40 G kA −1 current in the primary of the OH coils, at the plasma center.…”

“…The OH coils consist of the central solenoid with sets of compensating windings that are poloidally distributed around the VV to minimize the stray fields in the plasma volume [21,24,27]. This arrangement has been simulated with 2D axisymmetric in magneto-static mode using the FEM.…”

Design and construction of Alborz tokamak vacuum vessel system

“…The vacuum vessel provides a suitable condition for plasma shaping, baking, confinement, stability and supervising [6][7][8]. The vacuum vessel is designed to be capable of achieving the base pressure of 1 × 10 −5 Torr for the generation and confinement of the tokamak plasma, and also to be structurally capable of sustaining the vacuum pressure, the baking gas pressure, the electromagnetic (EM) loads during plasma disruption and the thermal loads during bake-out [9,10].…”

Preliminary Design of Alborz Tokamak

“…The magnetic field ripple is inversely proportional to the number of TF coils and by increase of their number is decreased [21]. Number of TF coils is normally about 12-36 coils [22,23]. The ripple magnitude due to the finite number of TF coils and the size of the ports of vacuum vessel, determine the number, size and shape of TF coils [24].…”
