Mapping Simulation — in concern with MA64 crosstalks Jaewon Park University of Rochester MINERvA/Jupiter Group Meeting, May 31, 2006

Contents Geant3-based simulation, QE event modHit, scintHit connector, bundle cable PMT box, pixel Only ID in active module is studied

What we expect There’s a strong possibility that hits from different planes (two X planes) go to one PMT V X U

Mapping stages 128  16 bundle Bundle index connector index Also keep track of relative index in each group Pre-map bundle and relative fiber position sequentially into 8x8 array We have flexibility that bundles can be mapped differently Finally apply interweaving pattern in 8x8 array

One red square is one PMT We need better mapping One red square is one PMT We can see that some hits are adjacent in clusters Only checked graphically
