In this work, we show the first measurements of an in-house developed, compact, high resolution, x-rayspectrometer. The prototype was tested in the XRF-D09B beamline at the LNLS (Campinas, Brazil), but is intended tobe used in the CARNAUBA beamline at SIRIUS. The spectrometer is a Wavelength Dispersive System (WDS) consistingof an integrated conical crystal analyzer and a position sensitive detector (Medipix detector) [1]. The proposedfocusing scheme [2] allows reducing detector area and optical aberrations thus making a very compact design (~16cm sample?detector distance), similar to that shown by Morishita et.al. [3].
