With the advent of 4th generation light sources (based on free electron lasers and energy recovery linacs), the need for high-quality electron beams became of utmost importance. The ultimate performance of such light sources relies on the characteristics of the beam from the injector. This tutorial represents a challenging attempt to cover within the time constraints, most of the relevant aspects of this important accelerator sub-system, from the requirements necessary to operate in 4th generation light sources, through the physics and dynamics of high brightness beams in the presence of space charge, to the description of the different injector schemes and sub-systems, including the advantages and limitations of the main technologies in use.
