Temperature diagnostics of Sulfur III plasma using collision-excitation model

Abstract

For accurate electron temperature diagnostics, the collision-excitation model is used for Sulfur plasma. Using the calculated Maxwellian average collision strengths at 1000 K, we calculate the electron temperature using the 3s23p2[Formula: see text]D1–3s23p2[Formula: see text]P3, 3s23p2[Formula: see text]S1–3s23p2[Formula: see text]D1 and 3s23p2[Formula: see text]S1–3s23p2[Formula: see text]P3 transitions of Sulfur III. Results show that when the line ratio of 3s23p2[Formula: see text]S1–3s23p2[Formula: see text]D1 and 3s23p2[Formula: see text]D1–3s23p2[Formula: see text]P3 transitions varies from 0.43 to 1, the electron temperature will vary from 0 to [Formula: see text] K, and the electron temperature will decrease with increasing line ratio. This discussion will be important for electron temperature diagnostics of plasma.
