Some decades ago, particle accelerators were controlled and optimized mainly by looking at viewing screens – mostly based on ZnS – and simple beam current meters. Developments in the field of beam diagnostics have paralleled the development of computers, sophisticated electronic circuits, and PCI systems. A consequence is the design of more and more complex machines, using powerful simulation programs to describe particle dynamics in modern accelerator structures. Nowadays, computer-aided operation and on-line control of modern accelerators, operated in a great variety of modes, require the availability of many beam parameters. Due to the manifold machines, such as linacs, cyclotrons, synchrotrons, storage rings, and transport lines, the demands on a beam diagnostic system can differ. Taking additionally the broad spectrum of particles, such as electrons, protons, and heavy ions into account, it becomes very clear that the development of versatile measurement techniques became essential in recent years. The main beam parameters and their meaning for characterization of particle beams are.
