Abstract :
The DIOSCUR tokamak is a superconducting machine using Nb3 Sn CIC coils and having a size similar to JET (Joint European Torus), although with a toroidal magnetic field of 7 T and a sustainable plasma current of 10 MA for long pulses (1000 s). The machine will have a divertor and great configurational flexibility in plasma aspect ratio up to A=5.2, current, up to 18 MA, and attainable poloidal β, to allow the study of stationary regimes and also the influence of bootstrap current. For CD and profile control, 50 MW of LH and negative ion beam power are foreseen. ICRF (ion cyclotron resonant frequency) heating and fast wave current drive have also been considered
