Beyond the collider
Specialized facility.
Not every experiment at CERN sits on the road to LHC collisions. These three run different beams, ask different questions, and answer them in different places.

Branch map
CERN is not one straight road.
These facilities use different beams and answer different questions. The map shows them as side branches instead of pretending they sit on the proton route to the LHC.
How they differ
Three beams, three questions.
The Antiproton Decelerator slows antiprotons for precision antimatter studies. ISOLDE creates short-lived isotopes and steers selected ion beams into nuclear-physics experiments. CLEAR is an independent electron accelerator for accelerator R&D, diagnostics, irradiation studies, and medical applications.
None of these are on the proton road to the LHC. They share the infrastructure at CERN but answer different scientific questions.
Branch route
These facilities sit beside the main learning path.
Use this section as a side branch, then return to the beam sequence or detector lab when you want the collider story.
