- 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
