Abstract

Spectra of highly-ionised krypton in the wavelength range 40-335Å have been observed in JET tokamak plasmas, into which small amounts of Kr were puffed. Among the observed lines are all the strong resonance lines within the n=2 shell from fluorine-like to lithium-like krypton, as well as all the stronger magnetic dipole lines that are expected to occur in these spectra. The wavelengths of the krypton lines were determined using known wavelengths of lines of elements intrinsic in the plasma, mostly carbon and nickel lines, as standards. In most cases of stronger lines, the accuracy is estimated to 0.025 Å, or better.
