Spectra of highly charged Ar, Kr, Xe and Fe ions, produced in an Electron Beam Ion Trap (EBIT), have been recorded in a broad x-ray energy band (0.2 keV to 10 keV) with a microcalorimeter detector. The first analysis of the Kr spectra has been completed and most of the spectral lines have been identified as transitions of B- to Al-like Kr. The transition energies have been determined with 0.2 % uncertainty. Asemi-empirical EBIT plasma model has been created to calculate a synthetic spectrum of highly charged Kr and to determine a charge state distribution of Kr ions inside the EBIT. Line intensity ratios of Fe XVII have been measured and compared with theoretical models.32.30.Rj, 34.50.Fa, 34.80.Dp, 32.70.Fw
