DUVEX a versatile EUV-X detector

A detector system has been developed for the soft x-ray and extreme UV ranges. It is called DUVEX and has been designed in order to be easy to implement and use, and cheap to operate. It consists in a YAG:Ce scintillator coupled to a photomultiplier module working in the counting mode. The system can be operated under vacuum. We report on the design and the performances of this detector in terms of response, noise, stability and efficiency. Soft x-ray spectra of different elements (from B to W) obtained in the wavelength dispersive mode acquitted with DUVEX are presented.
