Popis:	We made an inventory of krypton spectra over the wavelength range 3700–6000 A for the development of fusion plasma diagnostics. The measurements were performed using a prism spectrometer on the Lawrence Livermore National Laboratory low energy electron beam ion trap (EBIT II). With the electron energy from 150 to 17 000 eV, we recorded low ionization stages together with a number of magnetic dipole transitions from higher charge states. In total, we observed over 80 lines, of which about 70% of the lines have not been listed in the literature. This measurement established a baseline for future extension using spectrometers with very high resolution. As an example, we present the Kr spectra from 3770 to 3900 A measured with a transmission grating spectrometer that has a resolving power of about 15 000. Among the 41 lines observed, only six lines have been listed in the databases.
