The LiF detectors of a commercial device with the measurement range from 25
keV to 1.3 MeV were successfully used for of the monitoring X-ray from the
imploding liner plasma on the high current pulse generator S-300. The dete
ctor readings were discovered to decrease more than ten times behind a thin
lavsan filter of 2 mu m thick in comparison with the open detector reading
s. This result demonstrates a possibility of using the LiF detector for reg
istration of soft X-ray less than 1 keV. The detectors work in the regime o
f full absorption of the incident X-ray radiation up to the energy of about
10 keV. The stability of the detector readings under identical experimenta
l conditions allows one to use them for integral monitoring of the X-ray pl
asma radiation.
