| Abstract: | A discussion of laboratory spectra similar in temperatures and ion abundances to solar flare spectra is given. The laboratory spectra were obtained from high temperature plasmas produced by high power lasers and low inductance vacuum sparks. The current state of knowledge regarding line identifications in laboratory spectra is reviewed, and some of the results are used to identify lines in the high temperature solar flare spectrum in the 100 Å region and in the 1000 Å region. In addition, the physical dimensions and temperatures of the hot regions in the plasmas produced by the low inductance spark were recently measured, and a short summary of the results is given.A review paper given at the IAU Colloquium No. 27 on Ultraviolet and X-Ray Spectroscopy of Astrophysical and Laboratory Plasmas, held at Harvard University, 9–11 September, 1974.On leave from Tel-Aviv University, Tel-Aviv, Israel. |
