We present results of an XMM-Newton survey of the Chamaeleon I star forming region. In the five exposures we detected a total of 449 X-ray sources. Among them 96 are counterparts to the 138 spectroscopically confirmed members in the surveyed region; six of them have a spectral type later than M6.5 and are therefore classified as brown dwarfs. The spectra of the brighter sources were analyzed using a continuous emission-measure model composed of two power laws in temperature, as suggested fromfatcat:z2ho4a6455hidouggmtobha3hu
