  • 3D overview




  • Main features of the detector concept based on CMOS sensors. For each layer, the table indicates the radius, the pixel pitch, the read-out time, the ladder width, the number of ladders, the number of pixels, the instantaneous and average power dissipation.


Layer Pitch time r.o. N ladders N pixels Pdiss. (instantaneous) Pdiss. (mean)
L1 20 µm 25 µs 20 25M < 100 W < 5 W
L2 25 µm 50 µs 26 65M < 130 W < 7 W
L3 30 µm 200 µs 24 75M < 100 W < 5 W
L4 35 µm 200 µs 32 70M < 110 W < 6 W
L5 40 µm 200 µs 40 70M < 125 W < 6 W
total 142 305M < 565 W <29 W
