FIG. 1.

Schematic of the soft x-ray array diagnostics for KSTAR (top) and the structure of the filter wheel (bottom).

FIG. 2.

Line of sight of each detector element and the position of the Ar injector on midplane.

Image of FIG. 3.
FIG. 3.

Soft x-ray signal ratio as a function of T e . Be filters of 10 μm and 50 μm are assumed.

Image of FIG. 4.
FIG. 4.

Responsivity of the 50 μm Si detector with a pair of Ross filters. The difference between the two spectra can be used as a bandpass filter.

FIG. 5.

Soft x-ray signals of (a) channel 10 and (b) channel 12 during sawtooth oscillation (Shot 6306). (c) Time evolution of the soft x-ray signals from core to edge channels. Inversion radius lies on channel 11 (15 cm of radius) and the sawtooth period is 30 ms.

FIG. 6.

(a) Time evolution of the signal difference (Shot 6371). (b) Ar diffusion is seen after Ar puffing at 0.5 s. Bad channels 1, 5, and 13 are attributed to malfunctioning in the pre-amplifier electronics.
