[edit]

Detector Configuration

  • Geometry as of January 15, 2007
  • Double-Hit Resolution: 25 ns
  • Threshold: 0.8 MeV
  • Maximum Number of Hits: 100
[edit]

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.
