Caption: MODEL RELEASED. Gamma ray spectrometer. Researcher with a hemisphere of the Gammasphere gamma ray spectrometer. This 11 tonne machine's 110 germanium semiconductor detectors (behind man) circle a spherical target chamber (at right of man). From 1995-1997, the Berkeley Labs 88-Inch (2.24 metres) Cyclotron generated beams to impact nuclei in the target chamber. Gamma rays emitted by the deformed nuclei allowed physicists to probe the structure of matter. The portable device has also been used for research elsewhere. Photographed in March 1997, at Lawrence Berkeley National Laboratory, California, USA.
