The higher energy and intensity evolution of AdA, ADONE, started the study of the electron-positron collisions physics in Frascati.
The 1.5 GeV per beam, 105 m long storage ring was divided into 12 equal cells, each one consisting of a bending magnet followed by a quadrupole doublet and a straight section 2.5 m long. Four out of the 12 avalaible straight sections could host the experimental detectors devoted to the study of the beam collision products. The remaining 8 sections were used to place radiofrequency cavities, injection machinery and beam diagnostic tools. Throughout 24 years of operation, ADONE provided about 22.000 hours of colliding beam finalized to the study of processes generated by electron-positron interactions.
