Quiz
Three quick checks
Put the accelerator chain in order, pick the right detector for heavy-ion collisions, then tune a gravitational-wave signal until it shows above the noise.
Compare mode
Tune signal clarity
The same simplified model used in the gravity lab is reduced to two controls here. Lower noise, raise sensitivity, and watch the visibility score respond.

What each check verifies
The idea behind it
- The LHC is not the first machine in the chainSequence
- Detectors are built for specific collisionsSpecialization
- A real signal can be present but hard to seeVisibility

Send the beam to the LHC in the right order
OpenSelect each machine in accelerator order and check that the injector chain makes sense.
Current order: Position 1 → Position 2 → Position 3 → Position 4 → Position 5
Pick the best detector for heavy-ion collisions
OpenChoose which detector is most tuned for quark-gluon plasma and dense final states.
Heavy-ion collisions create dense particle sprays. Pick the detector designed to study that environment.
Tune the interferometer to reveal a chirp
OpenIncrease sensitivity and reduce noise until the signal shows above the background.
Reveal the chirp clearly enough to reach a visibility score of at least 68.
Current visibility: 36/100. Modeled strain: 9.41e-22.

What these checks test
The quiz checks whether the big ideas from the labs connect: acceleration prepares the event, detectors classify the aftermath, and signal processing decides what can be seen above noise.
Guided tour
Finish the path
Four steps: 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.
