The CORBA TRACY Interface

The TRACY[11] server provides access to the TRACY based model of the SLS transfer lines, booster synchrotron and storage ring. This includes methods to retrieve optics parameters for given machine settings and to perform model based corrections. The CORBA interface to TRACY provides access to the same machine model as used in offline simulations, permitting tested procedures to be employed for the optimization of the accelerator online. Table 1 shows a listing of a method that retrieves the optics parameters and corrector magnet values, as derived from an orbit correction procedure based on the orbit data associated with the vertical corrector magnets. The returned data are stored in a Tcl list which is unfolded through a Tcl procedure.
