CMS coordinate system

The conventional 3D coordinate system at the CMS detector with definition of the azimuthal angle φ. It is officially described in this paper. For more coordinate systems, please see the “coordinates” tag. For the definition of pseudorapidity, please see here. For more related figures, please see the Particle Physics category. For learning drawing 3D figures in TikZ, have a look at Chapter 40 of the TikZ manual, or the tikz-3dplot manual.

Minimal CMS coordinate system:
The CMS coordinate system, including the LHC and a compass (the z axis points to the Jura):
The ATLAS coordinate system, including the LHC:
CMS coordinate system with the a cylindrical detector:
