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

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

5. 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

6. 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

7. Occupancy
pixel occupancy in a PMT
