Importance of electron cyclotron wave energy transport in ITER

Abstract: The importance of electron cyclotron (EC) wave emission to the local electron power balance is analysed for various ITER operation regimes and, for comparison, for typical working conditions of FIRE, IGNITOR and the reactor-grade ITER concept as considered during the Engineering Design Phase (ITER-EDA). To cover the non-local effects in EC wave emission as well, the CYTRAN routine along with the ASTRA transport code is used. As a result, EC wave emission is shown to be a significant contributor to core electro… Show more

“…However, kinetic profiles are more difficult to simulate in real-time, partly because they evolve more rapidly but especially because first-principle models are not yet sufficiently developed to allow accurate and rapid simulation. Ad hoc models could be used in these cases, similar to those used in [36], for example. These models would have to be tuned depending on the plasma scenario, but given the experience operating today's tokamaks, reasonable results can be expected.…”

“…Возможная значимость ЭЦИ в локальном электронном энергобалансе в «стационарных» режимах рабо-ты токамака ИТЭР с высокими температурами в центре плазмы [8,9], а также в реакторе ДЕМО потребовала более аккуратного расчёта пространственного профиля плотности мощности потерь на ЭЦИ P EC (), усред-нённого по магнитным поверхностям (здесь радиальная переменная  -это квадратный корень из нор-мированного тороидального магнитного потока). При повышении температуры в центре плазмы до ~30 кэВ локальная мощность электронных циклотронных потерь становится немалой в сопоставлении с на-гревом термоядерными -частицами и почти сравнивается с дополнительным нагревом плазмы нейтраль-ным пучком P EC (0)  0,3P  (0)  P aux (0) [10].…”

“…Исследование стимулировано необходимостью развития методов предсказательного моделирования базовых сценариев работы токамака ИГНИТОР с учётом уникального опыта так называемого интегрированного численного моделирования таких сценари-ев для токамака ИТЭР (см., например, моделирование [5] с помощью общего транспортного кода АСТ-РА [6] и моделирование начальной стадии разряда c помощью общего транспортного кода ДИНА [7]). В таком анализе уместно использовать имеющиеся в литературе достаточно подробные результаты расчёта двух различных режимов работы токамака ИГНИТОР [8], полученные с помощью кода АСТРА. Целью…”

“…The latter, however, makes the radiative transport essentially nonlocal, and the identification of nonMaxwellian effects is feasible only for central plasma, with the highest temperature, because only this radiation has a peculiar spectral range (namely, high-number harmonics) in the spectrum of outgoing radiation. In contrast to the present day tokamaks, the EC wave emission by the plasma can significantly contribute to the local electron power balance in central part of plasma column for high temperatures expected in DEMO and steady-state regimes of ITER operation (see, e.g., [10], [11]). When central temperature increases to T e (0) ~30 keV the local EC power loss becomes a substantial part of heating from fusion alpha-particles and is close to the total auxiliary heating.…”
