Sketch of the Upstream view of the TIARA Barrel Detector showing (in blue) the detector numbers, (in red) the strip numbers within a given detector, and (in hashed red) the region that is shadowed by the target holder arm. The only Barrel channel with significant downstream shadowing, by the target holder arm, is Detector 6 Strip 1, and is marked by an arrow. The target holder is oriented at 60 degrees from the horizon; consistent with Bob's design.
