Effect of ICRH on the ion distribution functions evaluation of the ion temerature in the WEST TOKAMAK with ICRF heating

Abstract

Ion temperature measurements require sophisticated procedures such as charge-exchange recombination spectroscopy [1] or crystal spectroscopy [2] In the absence of such experimental data, the ion temperature estimation is obtained by reverse engineering of the total neutron yield, assuming the ion distributions are Maxwellian [3,4]. Ion distributions are no more Maxwellian when ICRH external heating is applied. Improvement of the procedure is proposed to account for ion Non-Maxwellian distributions by disentangling the thermal and fast components of the bulk ion distributions leading to a better estimate of the 'thermal-only' ion temperature The method uses a coupled wave / Fokker-Planck numerical solver and a neutron rate calculator coming from European Transport Simulator / Heating and Current Drive software [5,6] namely Cyrano / StixRedist / Fusreac [7,8] and is applied to the WEST tokamak [9,10]
