FEL II
/ Hillert, Wolfgang (speaker)
The subject of this advanced course is a simplified treatment of the light amplification process in a free electron laser (FEL).
The first lecture deals with the so-called low gain FEL, where a “short” undulator is surrounded by an optical resonator. Starting with the calculation of the energy exchange between the electron beam and the radiation field, the ponderomotive phase is defined which remains constant when operating on resonance. [...]

Longitudinal Beam Diagnostics
/ Bobb, Lorraine (speaker)
In these lectures an overview of the key diagnostics for transverse and longitudinal measurements of high brightness beams is presented. A variety of instrumentation for hadron and electron machines is reviewed with commentary of the advantages and disadvantages of each technique as well as some of the challenges facing diagnostics for future accelerators

Low emittance lattices
/ Martin, Ian (speaker)
The impact of lattice design on the natural emittance in an electron storage ring is discussed. The general expression for the equilibrium horizontal emittance in a storage ring is applied to the specific cases of storage rings constructed from FODO cells, double bend achromats, multi-bend achromats and theoretical minimum emittance lattices.

Beam loading
/ Damerau, Heiko (speaker) (CERN)
Radio-frequency (RF) systems in particle accelerators are usually designed to transfer energy to the beam or to define its longitudinal structure. However, charged particles passing through an RF cavity induce a voltage which acts back on themselves and on subsequent particles. [...]
