Abstract

A double-channel spectrometer with multilayer mirror has been built and operated on different experiments: the tokamak CASTOR and gas-puff Z-pinch at the Institute of Plasma Physics, Prague as a monitor of hot plasma line emission. Depending upon the mirror use, the spectrometer allows low resolution (λ/δλ=30) spectrum measurements in a wide energy range. Filter transmission as well as the reflectance of the disperse MLM elements and detector sensitivity were absolutely calibrated by an X-ray grazing incidence monochromator in the considered spectral ranges. A time resolution of line emission measurement of 0.1 ms for a low intensity source (tokamak) and better than 10 ns for a gas-puff Z-pinch has been achieved
