TheGammasphere is a third generationgamma ray spectrometer used to study rare and exoticnuclear physics. It consists of 110 Compton-suppressed large volume, high-purity germanium detectors arranged in a spherical shell.[1]
Gammasphere has been used to perform a variety of experiments in nuclear physics. Most experiments involve usingheavy ionnuclear fusion to form a highly excitedatomic nucleus. This nucleus may then emitprotons,neutrons, oralpha particles followed by a shower of tens ofgamma rays. Gammasphere is used to measure properties of these gamma-rays for tens of millions of such gamma ray showers. The resultant data are analyzed to gain a deeper understanding of the properties of nuclei.
Gammasphere was built in the early 1990s and has operated at the 88-inchcyclotron atBerkeley National Laboratory and atArgonne National Laboratory.
In the movieHulk, Bruce Banner is zapped by a machine called the Gammasphere. The actual Gammasphere, which detects rather than emits gamma rays, was used as a model for the device shown in the movie.[2]
