Various modifications of vacuum-ultraviolet (VUV) radiation detectors were developed, which included open CCDs (charge-coupled devices) and CCDs with one and two fiber-optical plates. A layer of phosphor P-43 (Gd2O2S:Tb) was deposited to the outer surface of the detectors. The sensitive surface of such detectors can have a complex, including curly, shape. The spatial resolution was studied in the visible range of the spectrum, and the absolute sensitivity of the detectors was measured in the VUV region of the spectrum (wavelength range λ=4.9-13.5 nm). The conditions of optimal use of detectors in VUV and X-ray spectrometers are considered. Keywords: fiber optics, luminescent (phosphor) detectors, VUV and X-ray spectrometers.
