The radiation emitted from highly charged tungsten ions has been measured at the Berlin Electron Beam Ion trap using high‐resolution x‐ray and EUV spectrometers. Highly charged tungsten ions ranging from Pm‐like to N‐like have been produced and excited in EBIT. The line emission originating from electric and magnetic dipole transitions is studied in a wide wavelength range from 0.12 to 80 nm. The results of our measurements are compared with predicted transition wavelengths from atomic structure calculations and observations at the ASDEX Upgrade tokamak. Here we focus on the quasi‐continuum emission around 5 nm from tungsten ions with an open 4 d shell (In‐like to Rb‐like ) and the L‐shell spectra of ions with configurations close to Ne‐like one.
