摘要：

Neutral density profiles are calculated for plasma and edge conditions consistent with those of the S-1 spheromak [Plasma Physics and Controlled Nuclear Fusion Research, 1984 (IAEA, Vienna, 1985), Vol. 2, p. 535]. Multiple generation charge exchange is the dominant transport mechanism for edge neutrals to the plasma center. Central neutral densities may be as high as 1%-5% of the electron density. The high-edge neutral population makes it possible to explain the value and scaling of resistivity in decaying spheromaks. Large neutral components also provide an ion energy-loss mechanism through charge exchange. © 1989 American Institute of Physics.
