Abstract
Emission lines which appear in the spectral ranges of ground state transitions from n = 2 levels in He- and H-like argon ions are discussed. X-ray transitions from elements commonly found in tokamaks (tungsten, molybdenum, iron and sulphur) which radiate in the wavelength range from 3700 - 4000 mA are identified by comparison with atomic structure calculations. Individual lines from tungsten charge states in the vicinity of Zn-like W^44+ are documented, along with B-like Mo^37+. The behavior of line ratios as a function of electron temperature is examined, in support of the identifications.
