A small-sized pulsed x-ray spectrometer was designed and developed. The spectrometer is designed to study pulsed x-rays in the energy range of quanta 1-30 keV. The spectrometer is an assembly of thermoluminescent LiF detectors arranged one after another. Thermoluminescent detectors record x-ray radiation and are used as filters for selection of x-ray radiation in the spectrum. Thermoluminescent LiF detectors are immune to electromagnetic interference, and their response is linear in a wide dynamic range of the absorbed radiation dose (from 20 mSv to 10 Sv). Calibration measurements and test tests have shown good performance and reliability of the small-sized spectrometer.
