Solving Complex Beamline Fitting and Optimization Problems with the Particle Beam Optics Lab (pbo Labtm)

A second generation of the Particle Beam Optics Laboratory has been developed with an emphasis on applications to problems in accelerator optimization. The new version of the software incorporates several enhancements that significantly extend the capabilities of the first release of PBO Lab described at EPAC98. Several charged particle optics programs, including TRANSPORT, TURTLE, MARYLIE and TRACE 3-D, are integrated with the new version. Three optimizers have been added as a new PBO Lab Optimization Module. Any optics model input parameter can be included in the set of optimizer variables, and any of the outputs from the computation engines can be used in the formulation of the nonlinear constraints and/or the objective (merit) function. The Optimization Module is described briefly and an application to a typical beamline problem is presented.
