TOCA: a highly user friendly application program for the tune, orbit, dispersion and chromaticity correction

In order to ease and speed up the intervention of the operators on the machine optics parameters, e.g. the orbit correction, a highly user friendly application program has been developed and fully used from the start of last year (1998). The program allows the acquisition and correction of the closed orbit, the dispersion, the tune and the chromaticity in the storage ring, and the acquisition and correction of the trajectory along the transfer line and the first turn in the storage ring, with a minimum intervention of the operator. The correction strengths are calculated using calculated theoretical optics or measured response matrix. The methods of correction implemented ate the SVD method and for the orbit and the trajectory also the MICADO method
