TOF I
- WBS 1.5.2.3.1
- 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
- dimensions (centimeters)
- standard: 2.54 x 6.00 x 252.00
- half-width: 2.54 x 3.00 x 252.00
- half-length (full-width): 2.54 x 6.00 x 120
- 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
- high rate counters
- inner two standard counters on both sides, both layers = 8
- all of the half-width counters = 8
- all of the half-length counters = 8
- PMT count for these = 2×(8 + 8) + 8 = 40
- Standard PMT count would be 176 - 40 = 136

- count per layer
- standard modules: 34
- three-quarter-width modules: 4
- half-width modules: 4
- half-length modules: 8
- totals (both layers)
- standard modules: 68 (Δ = −8)

- half-width modules: 8 (Δ = 0)
- half-length (full-width) modules: 0 (Δ = −8)
- half-length (three-quarter-width) modules: 16 (Δ = +16)
- sum of all modules: 100 (Δ = +8)
- PMT's
- all modules have two PMT's except half-length modules which have one
- count is 2×(100-16) + 16 = 184 (Δ = +8)
