Summary

Description
English: ARPES spectrometer measures angular dispersion in a slice α along its slit, so in order to map the band structure over a two-dimensional momentum space one needs to turn the sample, changing its roll/polar angle ϑ, pitch/tilt τ, or yaw/azimuth φ. Here, the change in polar and tilt angles is shown: ϑ=-25°, τ=+8°, -8°≤α≤8°.
