摘要：

The flattening of the electron density profiles due to the static magnetic island is observed when the n / m = 1 / 1 perturbation field is applied by the external coil. The iso-density widths are estimated from the model fitting analysis. The temporal history of the iso-density width and its dependence on normalized collision frequency and plasma beta are estimated from a single shot. The iso-density width increases as the external perturbation field increases. Although determination errors are not small compared with the dynamic range of the estimated iso-density width, the following tendencies are observed. The iso-density width shows positive dependence on logarithm of normalized collision frequency and negative dependence on beta.
