Twin Arm Dipole Spectrometers

The Twin Arm Dipole Spectrometers will guide the scattered particles from the interaction point to the detectors positioned in the focal plane of the magnetic system. The specific design of the spectrometer's magnets focus particles of different moment and scattering angle on different positions of the focal plane, thus effectively mapping those two variables on the cartesian coordinates of the focal plane. In this way it is possible to calculate the momentum and the scattering angle from an accurate, and potentially simpler, position measurement.
