EXOGAM (Acta Phys. Hung.: New Ser: Heavy Ion Phys. 11, 159 (2000)) is a powerful, high efficiency, gamma-ray spectrometer to study rare phenomena in nuclear physics produced in heavy ion induced reactions. EXOGAM detects the gamma-rays emitted during the de-excitation process of the highly-excited targeted nuclei produced in such collisions. It was specifically designed to exploit the exotic beams originating from the “Radioactif Ions Production and on-Line Acceleration System” (SPIRAL).
EXOGAM is a very versatile device used in a number of nuclear physics experiments involving stable or radioactive ion beams in the various experimental areas of GANIL. It is in general coupled to other devices such as the VAMOS or LISE spectrometers, neutron or charged particle detectors, to identify and/or select the nucleus of interest. The unambiguous assignment of gamma-rays to a nucleus and the measurements of their characteristic properties allows one to better understand the underlying nuclear forces at play.
EXOGAM is equipped with a full digital electronics based on the NUMEXO2 (NUMériseur pour EXOgam2) NIM digitizer, mainly developed at GANIL.
