The course gives an overview of the most frequently used beam diagnostics instruments at electron and proton accelerators, putting about equal weight to LINACs and synchrotrons. In addition, applications for their usage during operation and accelerator physics investigation are discussed.
The outline of the lecture is orientated on the beam quantities:
1- Beam current measurements using transformers, Faraday cups and particle detectors
2- Beam profile measurements using various methods, like scintillators screens, SEM-grids, wire scanners, residual gas monitors and synchrotron radiation
3- Transverse emittance measurements with slit-grid devices or reconstruction using quadrupole variation
4- The principle of rf pick-ups for beam position measurements as well as tune or other lattice function determinations
5- Longitudinal measurements of momentum spread and bunch structure using picks-ups, particle detectors or synchrotron radiation
6- Beam loss detection for beam alignment and machine protection.
Prerequisites: A good knowledge of general physics is required, as well as the basics in accelerator theory. The first year university mathematics is presumed, including matrix calculus, Fourier transformation and complex numbers. Only basic knowledge of detector physics, high frequency technologies and electronics is needed, more complex devices is discussed.
