Overview of Ignitor performance predictions

Abstract

Quasi-stationary subignited regimes are investigated for Ignitor using the JETTO transport code by controlling the isotopic composition of the plasma and applying appropriate pulses of additional heating to the plasma column. The analysis includes sawthooth oscillations that are expected to arise at the end of the current ramp-up. The two primary ion species (Deuterium and Tritium) evolve separately under independent inflows. The results of the simulations confirm that a careful balance between main iion inflow and RF power injection allows a large range of possibilities for producing sub-ignites discharges throughout the plasma current flatto
