3s{sub 1/2}-3p{sub 3/2} and 3p{sub 1/2}-3d{sub 3/2} transitions have been studied in potassiumlike W{sup 55+} through neonlike W{sup 64+} ions at the electron-beam ion trap facility in Livermore. The wavelengths of the lines have been measured in high resolution relative to well known reference lines from oxygen and nitrogen ions. Using the high-energy SuperEBIT electron-beam ion trap and an R=44.3 m grazing-incidence soft-x-ray spectrometer, the lines were observed with a cryogenic charge-coupled device camera. The wavelength data for the sodiumlike and magnesiumlike tungsten lines are compared with theoretical predictions for ions along the isoelectronic sequences.
