AFP and ALFA detectors as a momentum spectrometer system - feasibility study
We consider a possibility to measure a leading proton momentum using simultaneously the AFP and ALFA detectors. The idea is based on the simple fact that the proton trajectory through the magnetic field between the AFP and ALFA$_{1}$ detectors, depends on the proton's momentum loss $\xi$. The f...

Sumario: | We consider a possibility to measure a leading proton momentum using simultaneously the AFP and ALFA detectors. The idea is based on the simple fact that the proton trajectory through the magnetic field between the AFP and ALFA$_{1}$ detectors, depends on the proton's momentum loss $\xi$. The feasibility of the proton momentum measurement is directly related to the availability of the magnetic fields and their configuration, the overlap between ALFA and AFP detectors and their resolutions as well as energy losses and the multiple scattering effect that could wash away little actions from the magnets on the proton. |
