The characterization of x-ray laser radiation requires the measurement of the radiation wavelengths, their brightness, and their temporal evolution. The spectrometer used for this application includes a focusing, grazing-incidence ellipsoidal mirror, a transmission grating for spectral resolution, and a soft x-ray streak camera to time-resolve and record the spectrum. This paper describes the bench alignment of the spectrometer and its alignment at the laser facility before each shot. Particular emphasis is put in the fact that only optical techniques were used for both alignments, relying on the correlation between the behavior of each component at optical and x-ray wavelengths.
