FST Hybrids

Numbers and Coordinates for the BST/FST Upgrade

View on the FST hybrids (from 'backward' direction!):

left of the middle the v-detector (i.e. on the forward face of the wheel),

right of the middle the u-detector (i.e. on the vertex face of the wheel),
Both (u- and v-) detectors and hybrids are of the same type but mounted back-to-back.

to the left and right r-detectors which appear for disk 1 and 3 only (and are actually mounted on separate - single-sided - wheels).

The '1st strip' w.r.t. the readout sequence is marked.
