  • Threshold: 0.8 MeV
  • Maximum Number of Hits: 100

Items for Discussion

  • There seem to be no hits for bars 41-44. Software bug?

Yes, it was a mismatch between the names used in the hdds geometry document and those expected in the simulation hits package. This bug was fixed by RTJ on 16-Jan.


The characteristic background rate per PMT per bar in the TOF.
The energy deposition in the TOF for background hits. There are no surprises here -- log( 2.54 cm * 0.002 GeV / cm ) = -2.3
