Investigation of impurity transport using laser blow-off technique in the HL-2A Ohmic and ECRH plasmas |
Time evolutions of total impurity density profiles, obtained from simulations of (a) Ohmic and (b) ECRH discharges, with the unit being m−3. Total impurity density profiles (c) in the Ohmic case and (d) in the ECRH case at respective time, |
