Basic Design Ideas
Full acceptance in phase space on both arms, i.e. the physics of
rapidity gaps should not be compromised.
The magnetic architecture of the experiment should be integrated into
the design of the LHC
machine lattice.
Diffractive proton measurements on both sides for :
.
Measurements of elastically scattered protons on both sides for : .
Multiple magnet spectrometer with overlapping acceptances. Define tracks
in the previous magnet and improve their momentum resolution in the
following one. High momentum forward charged particles are bent out of the
beam and their momenta are measured with detectors close to the beams.
Measurement of photons reasonably uniform over the complete phase space.
Full calorimetry ( with gamma detection) requires coordinated interplay
with tracking and a zero degree calorimeter between the beams.
Muon identification in the forward arms.
Cost minimization by the use of existing magnets
(Aleph solenoid, and UA1
magnet) and exploitation of stageability.
Optimal use of Intersection Region IP4,
including caverns and infrastructure at mimimal cost.
