High density plasmas (n0 ≈ 8 × 1020m-3) featuring steady improved core confinement have beenobtained in FTU up to the maximum nominal toroidal field (8 T) by deepmultiple pellet injection. These plasmas also feature high purityefficient electron-ion coupling and peaked density profiles sustainedfor several confinement times. Neutron yields in excess of 1 × 1013 n/sare measured, consistent with the reduction of the ion transport toneoclassical levels.

高密度プラズマ(n0 ≈ 8 × 10^20 m^-3)は、深部多重ペレット入射により、FTUにおいて最大公称トロイダル磁場(8 T)まで改善された定常的なコア閉じ込めを特徴とする。これらのプラズマはまた、高純度、効率的な電子-イオン結合、および複数の閉じ込め時間にわたって維持されるピーク状密度分布を特徴とする。1 × 10^13 n/sを超える中性子収率が測定され、これはイオン輸送の新古典レベルへの低減と一致する。
