FTU offers the unique opportunity to explore a broad range of collisionality [1] expressed as ν_eff = 0.1 Zeff 〈ne〉 R / 〈Te〉^2.
This work is devoted to study the dependence of the electron density profiles and peaking in a low collisionality regime, more interesting for comparison with other tokamaks [2]. With respect to those indeed, FTU features a wider scale of magnetic fields and densities. This allows to analyse the behaviour of the electron density profiles as a function of magnetic field and plasma current, investigating also more factors, such as: wall conditioning, plasma temperature.
