Spectra in the 70 A - 345 A Wavelength Region of Elements Injected into the PLT Tokamak
Abstract
High resolution spectra of the elements Fe, Mi, Zn, Ge, Se, and Mo injected into the PLT tokamak have been recorded by the 2 meter Schwob-Fraenkel soft x-ray multichannel spectrometer (SOXMOS). Spectra were recorded every 50 ms during the time before and after injection. The spectral lines of the injected element were very strong in the spectrum recorded immediately after injection, and the transitions in the intrinsic elements (mostly Fe, Ti, and Cr). An accurate wavelength scale was established using well-known reference transitions in the intrinsic elements. The spectra recorded after injection, and the resulting spectrum is composed almost entirely of transitions from the injected element. A large number of delta n=0 transitions in the Li I through K I (except Ne I) isoelectronic sequences of the injected elements were identified in the wavelength region 70 A to 345 A. (jhd)
