Abstract
The Euroball Cluster detector consists of seven closely packed hexagon al encapsulated germanium detectors which are mounted in a common cryo stat and surrounded by a EGO suppression shield, By adding back the Co mpton scattered events between the seven germanium detectors the detec tor system behaves similar as a single germanium detector with a volum e of 2000 cm(3). The response of this very large germanium detector to gamma-rays up to 10 MeV has been measured using a short lived Al-24 s ource produced at the Cologne FN Tandem accelerator. At 10 MeV the eff iciency of the Cluster detector is nearly one order of magnitude large r than that of a 30% germanium detector.
