I am reading about the instrumentation of Advance Compound Explorer (ACE). Cosmic Ray Isotope Spectrometer(CRIS) is used to detect the isotopes of energy range 100-600 MeV. I understand the mechanism for detection. A scintillating hodoscope followed by the silicon detector is used for the detection process. Here hodoscope is used to trace the trajectory of particle, while Silicon(Lithium doped) detector used to measure the charge and mass of particle. The charge and mass measurement has a link with the energy loss by the particle in silicon detector as well as the incident energy of particle.
Does the energy of particle remains unchanged when it passes through the hodoscope? If yes then how?
The kinetic energy is unchanged when a particle moves in a uniform magnetic field because the velocity of the particle isn't affected by a magnetic field.
