Generic Automated Beam Steering and Beam Shaping Programs with an Object Oriented Approach

The acceleration of the high brightness beam for the Large Hadron Collider (LHC) in the pre-injectors, which will operate at the limit of their performance, will demand that even small perturbations of beam trajectory, orbit and beam shape are corrected on a daily basis. The corrections applied have to be based on the existing machine model to avoid a slow drift of the machine parameters away from the nominal values. To help the operators in this work, Automatic Beam Steering and Beam Shaping (ABS) application programs are being introduced. We will present the development of a generic and modular software for this purpose. The aim is to end up with a data-driven, portable application package, that has a common look for the different machines and transfer lines, and for the different types of corrections for which it applies. The programs have interfaces to several different instrumentation devices, normally external software applications, used to measure the actual beam positions or shapes. For calculation of new machine settings, the programs use the CERN developed Mathematica program Beam Optics.
