1. MINERvA Simulation - HCAL and ECAL Calorimetry Jaewon Park University of Rochester Jupiter/MINERvA Group Meeting, Oct 4, 2006

2. 2 More Different OD slots OD frame size is kept constant V6, V7 has one more slot than V4 Having more slot means less interaction material within limited space V9 is a extreme case of V6 and V7 V8 is similar to V4 More slots have no gain V8 is a simpler design to make orig5.72 11.43 17.1545.74 v15.72 11.43 45.73 v457.3859.7712.155 11.4345.74 v66.86 11.4345.73 v755.936.867.798.72 11.4345.73 v85512.15 11.4345.73 v94.2875 11.4345.73 Slot sizes

3. 3 Theta dependence with 3GeV, 5GeV Old data used 2.2GeV Try with higher energy Leakage is a function of proton beam energy More leakage on higher energy Is it fair to use a=1.3 for higher energy?

4. 4 Finding calibration const with infinite OD 2.2GeV5GeV Orig geom + 5cm x 19 layers Previous a=1.3 was found with 2.2GeV proton beam a=1.2 seems best with 5GeV Try to make total energy constant

5. 5 Trying leakage correction Relative calibration const for OD=1.625 intead of 1.3 Theoretically wrong, but it seems to work Better way is using interaction length but it’s a function of energy

6. 6 Detector Logical Region Scint only ECAL HCAL Nucl. target For HCAL study, lead can be ignored For theta=0deg, particle will hit DS-HCAL. For theta=40deg, it passes both DS-HCAL and OD

8. 8 Interaction length as function of theta ID DS OD ID DS+OD ID ID+DS+OD

9. 9 Interaction length: Comparison with data 2.2GeV V4 OD E_od is 1.3 times scaled Tried to make leakage correction with interaction length but haven’t succeeded yet

10. 10 Interaction length: Comparison with data 5GeV proton V4 OD E_od is 1.3 times scaled

11. 11 Thicker ECAL Add high theta data point 3mm lead gives ~5% decrease on resolution (previously estimated ~10%) It’ll interesting to try with different OD slot position
