- Classification
- forward physics
- Topology
- Near-beam Roman pots at ±220 m
Event signature
How a collision looks in this detector.
Small-angle traces and low-angle showers.
Purpose
Probe proton structure and scattering near-beam angles.
What it does

Guided tour
Guided learning path
A four-step arc: follow the beam, see the aftermath, compare with spacetime signals, then test your intuition.

Follow the beam
Start with the injector chain so the rest of the site follows a physical sequence.
Open - 02 · You are here
See the collision aftermath
See which detectors catch which particles after a collision.

Compare with spacetime signals
Switch to gravitational waves: tune mass, distance, and noise to find the signal.

Test your intuition
Short quizzes on accelerator ordering, detector choice, and signal tuning.
