Physics and Technological Issues for Steady-State Tokamak Operation on TRIAM-1M

Steady State Experiments on High Performance, Current Profile Control and Long Sustainment of LHCD Plasmas on the Superconducting Tokamak TRIAM-1M

TRIAM-1M (R0 =0.8 m, a×b=0.12 m×0.18 m and B = 8T) has the main mission to study the route toward a high field compact steady state fusion reactor. We have advanced steady state operation (SSO) programme in tokamaks, studied a heating mechanism for the high ion temperature (HIT) mode with an internal transport barrier, obtained an enhanced current drive (ECD) mode in an extended (higher power a...

Control of advanced scenarios for steady-state tokamak operation

Physics of plasma control towards steady-state operation of ITER

ITER is a fusion experimental reactor to show scientific and technological feasibility of fusion energy. It is designed to produce fusion power of 500MW for 300-500 seconds with fusion energy gain Q at least 10 (Q ≥10) [1], [2]. ITER should show scientific and technological feasibility of fusion energy as one step to DEMO, which produces electricity by fusion energy. Although design of DEMO wil...

Steady-State Operation

A major upgrade of the Tore Supra heat and particle exhaust capability, known as the CIEL project [P. Garin et al.,this conference] and installed during the year 2000 shutdown, will raise the heat exhaust capability to 25 MW (convected + radiated) steady-state, and the pumping capability to -4 Fa.m3/s, and will allow Tore Supra to investigate high power steady-state plasma operation, with targe...

Integrated plasma physics modelling for the Culham steady state spherical tokamak fusion power plant

Integrated modelling of important plasma physics issues related to the design of a steady-state spherical tokamak (ST) fusion power plant is described. The key is a steady-state current drive, and 92% of this is provided by a combination of bootstrap and diamagnetic currents, both of which have a substantial toroidal component in a ST. The remaining current is to be provided by either neutral b...
