1 Results from Non-proj Geom Guilherme, Jeremy and Vishnu

2 Sampling Weights Determined from 10 GeV charged pions Minimize: (1/N)  (E 0 – a i L i ) 2 where E 0 is the incident energy a i is the weight for layer i L i is the energy/number of hits in lyr i For simplicity i=2 considered here

3 Energy Resolution single threshold

4 ZZ events Fitted width

5 ZZ events RMS

6 Analog

7 Digital

8 Sampling Weights GISMO (projective) Analog  64.5 (EM) 16.2(HD) Digital  0.0332 (EM) 0.0715 (HD) G4 (non-projective) Analog  84.2 (EM) 17.6 (HD) Digital  0.044 (EM) 0.085 (HD)

9 Energy Resolution (non-proj) single threshold

10 Energy Resolution (non-proj) dual threshold

11 Proj vs Non-proj

12 Comments The gain in going to non-projective geom is about what we expected (~20%) But we are not comparing the same thing SDMar vs SDJan GISMO vs G4 EMCal sampling is different Need to convert these to jet resolutions
