Abstract
A stack of annular detectors made of high-purity germanium was developed. The detectors are position sensitive with radial structures. The first one ("Quirl") is double-sided position sensitive defining 40 000 pixels, the following three (E1, E2 and E3) have 32 wedges each. The Quirl acts as tracker while the other three act as calorimeter. The stack was successfully operated in meson production reactions close to threshold.
