We first discussed the the two stripes on the 2d plot - r vs z of the vertex position. The upstream one is at the downstream CDC plate. The other stripe is in the middle of the first package (not clear why?). This may indicate background from photons(?) stopping in the CDC plate that has an inner radius of ~10cm; for r<10cm the photons are stopped in the first package. Eugene: e+/e- from the photon conversion can't be separated without magnetic field. |
