1. Detectors are made out of two sensors, each sensor is made out of one 6" wafer.

2. The sensitive area of each sensor is w = 93.696 mm wide and l = 91.514 mm long. The width corresponds to a pitch of 122 or 183 microns when the sensor is equipped with 6 or 4 APVs, respectively.

3. The insensitive region is dl = 1.5 mm along the strips, and dw = 1.35 mm in the direction orthogonal to the strips.

4. In addition a gap = 0.1 mm is needed between the two sensors.

This gives the physical dimensions for the detector:

• L_tot = 2*l + 4*dl + gap = 189.128 mm

• W_tot = w + 2*dw = 96.396 mm
