Soft x-ray spectroscopy of laser-produced plasmas with a convex mica crystal spectrometer

The application of a convex mica crystal spectrometer to soft x-ray spectroscopy of laser-produced plasmas is discussed. Photographic spectra were obtained with resolving power 1500 and show isoelectronic scaling of oxygen-, nitrogen- and neon-like ion spectra of copper, zinc and gallium in the spectral region 8 to 13 A. Photoelectric continuum measurements were made in the same spectral region as an electron temperature diagnostic for low Z targets. Line classification and plasma diagnostic possibilities are considered. (author)
