The Gammasphere is a third generation gamma ray spectrometer used to study rare and exotic nuclear physics. It consists of 108 Compton-suppressed large volume, high-purity germanium detectors arranged in a spherical shell.〔(), Gammasphere Online Booklet〕 Gammasphere has been used to perform a variety of experiments in nuclear physics. Most experiments involve using heavy ion nuclear fusion to form a highly excited atomic nucleus. This nucleus may then emit protons, neutrons, or alpha particles followed by a shower of tens of gamma rays. Gammasphere is used to measure properties of these gamma-rays for tens of millions of such gamma ray showers. The resultant data is analyzed to gain a deeper understanding of the properties of nuclei. Gammasphere was built in the early 1990s and has operated at the 88-inch cyclotron at Berkeley National Laboratory and at Argonne National Laboratory. In the movie Hulk Bruce Banner is zapped by a machine called Gammasphere. The actual Gammasphere, which detects rather than emits gamma rays, was used as a model for the device shown in the movie.〔(), ScienceDaily: Gammasphere Featured In New 'Hulk' Movie〕 == See also == * Canadian Penning Trap Mass Spectrometer * Helical Orbit Spectrometer (HELIOS) 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Gammasphere」の詳細全文を読む スポンサード リンク
