1. 1 Calorimetry Study Update — Angle dependence with cut Jaewon Park University of Rochester MINERvA/Jupiter Group Meeting, May 03, 2006

2. 2 Primary vertex position dependence Proton K.E=2.2GeV, theta=50deg “ID distance 50cm” means 50cm closer to OD Mean shift is uncalibrated resolution mean id distance Cut:

3. 3

4. 4 Theta dependence Proton K.E=2.2GeV, phi=0deg, no eCal, OD and DS-HCAL 37deg hits corner, i.e., where inner faces of OD and DS- HCAL meet

5. 5 Combining theta and Phi dependence Proton K.E = 2.2GeV, theta=50deg There seem to slight leakage in the region of phi=20-30deg P0 -0.32 P1 -0.028 P2 -8.9 Uncalibrated res mean (OD only) P0 -0.57 P1 -0.024 P2 -11
