Visible spectroscopy at the Extrap-T1 pinch experiment

Technical Report:

Abstract

A wide range UV to visible spectrum from 2450 to 8050 Angstrom has been acquired and analysed for the EXTRAP-T1 plasma. The impurity lines in the spectrum are mainly from carbon and oxygen species up to four times ionized, but also nitrogen lines are present. No traces of metal impurity are observed. We have identified most of the spectral lines and compare intensities from several multiplets with predicted values. A spectral range free from line emission is found which is suitable for continuum measurements. Furthermore, line strictures are identified as originating from the CH molecule and are observed both using a center chord line of sight and an edge chord line-of-sight through the plasma. (au).
