We investigated the exit charge, scattering angle and energy loss distribution of heavy ions (30 MeV carbon) planar channeled in a thin crystal. We measured, in a list mode, exit charge qex, scattering angle θex with respect to the (110) channeling plane, and energy loss ΔE, for each heavy ion of incident charge qin and incident angle θin, and obtained a distribution Y(θsc,qex,ΔE;θin,q in). As a single crystal, we adopted a thin totally depleted Si detector of 4 μm in thickness, and we measured the energy loss by the signal of the detector itself. After passing through the sample crystal, the exit charge and angle of the ions were measured with a 2D position sensitive detector coupled with a slit and an electrostatic deflector. Close correlations among the exit charge, energy loss and exit angle were found.
