The fully non-inductive spherical tokamak EXL-50, built and operated by the ENN private limited company, has routinely achieved high current drive efficiency of ∼ 1 A/W in only ECRH powered experiments. We have numerically investigated the effectiv

The hot-tail mechanism of runaway electron (RE) production (Harvey et al 2000 Phys. Plasmas 7 4590) is the primary source of RE in the case of rapidly cooling tokamak plasma. Quantifying this mechanism is very important as it can provide most of the

In this paper, a similarity relation between RF wave systems in tokamaks is found theoretically by investigating scaling conditions of plasma density and temperature, tokamak size and background magnetic fields, and RF wave frequency and power. The s
