There is only a very weak correlation between the momentum and the scattering angle.

These protons cannot be detected in the main detector. The standard detectors used to detect the scattered proton are roman pots placed at different distances from the IR.

Using this detector technology poses an other requirement on the machine performance. To reach as small scattering angles as possible a small emittance of the beam is crucial as  there is also an additional requirement of 10 sigma clearance from the core of the beam.
