Abstract Measurements performed on the SuperACO storage ring showed that, during the decay of the beam, the inherent synchrotron oscillation remains dipolar but the frequency of this oscillation depends on the remaining current in the storage ring. Three distinct regions of current were characterized. In the region of high current (100{endash}200 mA), the frequency was constant and was three times the synchrotron frequency. At an intermediate current (70{endash}100 mA), another constant frequency was present, two times the synchrotron frequency. In the third region (30{endash}60 mA), at low current, the frequency was proportional to the square root of the current, and was higher than the two frequencies above. The synchrotron band in the frequency spectrum contained several lines which confirmed the presence of at least one passive cavity and maybe of a second one at two well separated frequencies. They induce self-consistent micro structures in the bunch. {copyright} {ital 1996 American Institute of Physics.}
