Electron cyclotron heating versus neutral-beam heating: a comparison on a tokamak ignition experiment

R. Cano, A. Cavallo, H. Capes1981年被引用 5Nuclear FusionIF 3出版社

Using a detailed system of computer codes, astudy has been made of electron cyclotron heating andneutral-beam heating on a large tokamak ignition experiment. – For the case of Intor (B = 50 kG, R = 4.5m, a = 1.5 m, e=1.11 × 1014 cm−3, Zeff = 1), the power required for ignitionusing two different energy confinement scaling laws wascalculated for each heating method. Because of the centralenergy deposition and the peaked temperature profiles obtainedwith electron cyclotron heating, the energy needed to achieveignition using this heating method was about a factor of fourlower than that needed using 200-kV neutral beams.

詳細なコンピュータコードのシステムを用いて、大型トカマク点火実験における電子サイクロトロン加熱と中性粒子ビーム加熱について研究が行われた。– Intorの場合(B = 50 kG、R = 4.5 m、a = 1.5 m、e=1.11 × 1014 cm−3、Zeff = 1)について、2つの異なるエネルギー閉じ込めスケーリング則を用いて、各加熱方法に必要な点火パワーを計算した。電子サイクロトロン加熱によって得られる中心部へのエネルギー堆積と尖った温度分布のため、この加熱方法を用いて点火を達成するのに必要なエネルギーは、200 kV中性粒子ビームを用いる場合に必要なエネルギーの約4分の1であった。
