Abstract :
The agreement between the DAΦNE model and the measured machine parameters (betas, dispersion etc) has further improved in the 2002 runs. A better dispersion function control has been obtained by modifying the closed orbit correction algorithm, which now includes corrector strength minimization. The model has been integrated in the accelerator control system, providing a faster and reliable tool for fine and on-line machine optics tuning. New measurements, such as the machine second order dispersion, have proved to be very effective in studying the second order terms in the rings. Measurements of second order chromaticity and tune shift on amplitude have extended our knowledge about the lattice up to the third order.
