WLS Fiber Trapping Efficiency

Data collected here was reanalyzed. This should be compared to computational data presented here.

Experimental Data
Figure 1: Data collected by Hannah/Alex
The percentage 100*(w/ mask peak)/(w/o mask peak) is (17.2±3.8)%.

• Possible reasons:
  • QE spectrum was given for 1800V, measurements at 2000V
  • Pencil beam of muons
  • Relative geometry of football-shaped sample
