REACTOR RELEVANT ICRF HEATING IN JET D-T PLASMAS

摘要

Ion Cyclotron Resonance Heating (ICRH) experiments have been carried out in reactor relevant scenariosrnduring the Deuterium-Tritium (DTE1) campaign in JET. For the first time it has been possible to assess the deuteriumrnminority in tritium plasmas (D)T scheme: this produced a steady-state DT fusion power up to 1.66 MW forrninput ICRF power of 6 MW. Strong ion heating, with core ion temperature up to 13 keV, has been observed whenrnusing ~3He minority heating in both 50:50 D-T and tritium dominated H-mode plasmas. Second harmonic tritiumrnheating has also been studied and, as expected for JET plasma conditions, it has produced mainly electron heating.rnFinally, the inverted scenario of tritium minority in deuterium (T)D was successfully demonstrated.
