ARPES spectrometer accepting electrons emitted into polar angle ϑ and ±8° around.

Summary[edit]

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 angle is shown: ϑ=-25°, τ=0°, -8°≤α≤8°.

 This diagram uses embedded text that can be easily translated using a text editor.
This SVG diagram contains embedded raster graphics.[1] Such images are liable to produce inferior results when scaled to different sizes (as well as possibly being very inefficient in file size). If appropriate to do so, they should be replaced with images created using vector graphics.
Note: This template is only supposed to be used if the SVG file mixes vector and raster graphics. If the SVG file only contains raster graphics {{FakeSVG}} is supposed to be used. See also {{TopoSVG}}.
