'''This poses the following requirement that for different hadron beam energies 100 GeV and 250 GeV protons with a momentum 20\% lower then the beam energy and a scattering angles up to 12 mrad need to be transported through the different magnets.'''
X mrad need to be transported through the different magnets.

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.
