nStrips depends plane orientation (X,U,V)

Single gamma event sample

Vertex: Vr<50cm Perpendicular:

Parallel:

nStrips only increases when angle between particle scintillator strip increase perpendicularly.

Proton tracking efficiency – angle dependence

Proton is mostly forward Vertex range selection doesn’t

improve efficiency?

Vr<50cm

Comparison between

no selection and Vr<50cm

4

Muon tracking efficiency – E,angle dependence

Muon tracking efficiency is pretty good.

Vertex range selection improved efficiency.

Vr<50cm

Comparison between

no selection and Vr<50cm
