Reply to "Comments on the paper 'Characteristics of high-density tokamak ignition reactors'"

According to Galvão, the .values chosen for limiter safety factor (qa = 2.5) and poloidal beta (βp = 0.5 R0/ap) in our illustrative examples of compact, high-density, high-field tokamak operation [Nucl. Fusion 1976 16 31] may be too optimistic for plasmas of non-circular cross-section. Galvão's treatment, however, applies only to elliptical plasmas. In fact, MHD-stability analysis shows that plasmas of D-shaped, doublet, and rectangular cross-sections are stable at lower values of q than are available to elliptical plasmas of the same shape factor, S.

Galvãoによれば、コンパクトで高密度、高磁場のトカマク運転の実例[Nucl. Fusion 1976 16 31]において選択されたリミター安全係数(qa = 2.5)とポロイダルベータ(βp = 0.5 R0/ap)の値は、非円形断面のプラズマに対しては過度に楽観的である可能性がある。しかしながら、Galvãoの取り扱いは楕円形断面のプラズマにのみ適用される。実際、MHD安定性解析によれば、D字形、ダブレット形、および矩形断面のプラズマは、同じ形状因子Sを有する楕円形断面のプラズマで利用可能なqの値よりも低いqの値で安定である。
