  • number of layers: 2
    • horizontal and vertical orientation
  • if no special modules, would be 42 counters per layer
  • special modules take up 4 standard module spaces per layer
    • two standard spaces: half-width modules
    • two standard spaces: half-length modules
  • count per layer
    • standard modules: 38
    • half-width modules: 4
    • half-length modules: 4
  • totals (both layers)
    • standard modules: 76
    • half-width modules: 8
    • half-length modules: 8
    • sum of all modules: 92
  • PMT's
    • all modules have two PMT's except half-length modules which have one
    • count is 2×(92-8) + 8 = 176
