FSSR mica spherical crystal spectrometer with CCD detector for high-resolution x-ray spectroscopy of femtosecond laser produced plasma

The use of the FSSR mica spherical crystal spectrograph with CCD detector to study satellite structures of 1s 2 –1s2p transitions of [He]-like Al ions and fine structure of Kα-lines is presented. It is shown that the FSSR spectrograph is more suitable for study of laser plasma with high spectral and spatial resolution than other types of spectrographs and the use of this spectrograph gives the possibility to measure the sizes of the x-ray sources and the intensity of the dielectronic satellites.
