Abstract. A new reduced size ITER-RC superconducting tokamak concept is
proposed with the goals of studying burn physics either in an inductively
driven standard tokamak (ST) mode of operation, or in a quasi-steady state
advanced tokamak (AT) mode sustained by non-inductive means. This is
achieved by reducing the radiation shield thickness protecting the
superconducting magnet by 0.34 m relative to ITER and limiting the burn mode
of operation to pulse lengths as allowed by the TF coil warming up to the
current sharing temperature. High gain (
Q 
10) burn physics studies
in a reversed shear equilibrium, sustained by RF and NB current drive
techniques, may be obtained.
