Edge parameters and scrape-off layer (SOL) characteristics in IGNITOR
IGNITOR is a high field tokamak conceived to reach ignition. The ignited scenario considers operation at average density around 6 x 1.0 E20/m3 and average temperature about 5 keV. The scrape-off layer (SOL) plasma properties are, as a consequence, very different from those of present machines. Based on extrapolation from FT and other limiter machines and using self-consistent global models, the SOL properties in IGNITOR are l(n) about 0.01 m, density at the last closed flux surface (LCFS) 2.5 x 1.0 E20/m3 and temperature at the LCFS lower than 60 eV. All the parameters have a small dependence on the radiated power. In addition, a strong screening of the SOL results from the calculations.
