3 Theta dependence with 3 Ge. V, 5 Ge. V l l l Old data used 2. 2 Ge. V 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 Finding calibration const with infinite OD 2. 2 Ge. V 5 Ge. V Try to make total energy constant Orig geom + 5 cm x 19 layers l Previous a=1. 3 was found with 2. 2 Ge. V proton beam l a=1. 2 seems best with 5 Ge. V l

5 Trying leakage correction Relative calibration const for OD=1. 625 intead of 1. 3 l Theoretically wrong, but it seems to work l Better way is using interaction length but it’s a function of energy l

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

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

9 Interaction length: Comparison with data 2. 2 Ge. V l V 4 OD l E_od is 1. 3 times scaled l Tried to make leakage correction with interaction length but haven’t succeeded yet l

10 Interaction length: Comparison with data 5 Ge. V proton l V 4 OD l E_od is 1. 3 times scaled l

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