Beam physics and diagnostics

In this paper new goals for particle beam diagnostics are discussed in contrast to traditional applications. New accelerator design ideas to produce particle beams of high performance characteristics require a redefinition of beam diagnostics toward more sophisticated beam control and more automation in beam measurements and analysis. New accelerator design concepts are more and more based on the ability to match the actual accelerator to the theoretical model in order to allow the adjustment of parameters which are not directly controllable. Scenarios of possible developments in beam diagnostics in support of future particle accelerators will be discussed with the goal to envision beam diagnostics and control systems which can greatly reduce the involvement of accelerator operators by performing and analyzing well known and repetitive beam measurements faster, more accurate, and consistent.
