X-ray crystal spectrograph for the laser-plasma experiments
X-ray spectral lines emitted by high temperature plasma can be taken by means of crystal spectrograph in laser-plasma experiments. Spaoe-integraied and space-resolved x-ray crystal spectrograph developed and used in onr laboratory are described in this paper. X-ray diffraction crystal is "the main pari of the speotrograpli。 The integratod roflection coefficient, peak diffraction efficiency7 crystal broadening and hoinogonoity of ihe crystal have been deiermined experimentally. In addition, linear dispersion and instrumeni broadening have also been estimated by some experiments. Tho oharao ieristio curves of the X-ray film have been obtained by several mothods. The windows of ihe spectrograph are aluminized Formyar films which, have high transmission in soft X-ray region. This is one of the distinguishing features of our spectrograph. Some typical space-integrated and space-resolved spectra of He-like and Η-like ions of sodium and silicon in 5~13 A obtained in our experiments are presented, in Lite end of this paper.
