摘要

<正>The visible light of argon plasma produced by the electron cyclone resonance ion source (ECRIS) with wavelength from 300 to 900 nm has been detected by Spec-pro 500i, a grating spectrometer. A great amount of the character lines were emitted when the arc starting. Most of these lines can be identified and were from argon atom and ions with lower charge states such as 1+, 2+ or 3+. A small fraction of unknown lines was possibly from argon ions with higher charge states which needs to be investigated later. Fig.1 shows part of the results, and the referring lines are compared with the up-to-date data from NIST (the National Institute of Standards and Technology) in Table 1.
