Space charge is one of the main limiting factors for low-energy and high-brightness machines. The course approaches space charge from the incoherent perspective to showcase how effects such as the space charge tune spread and the space charge driven resonances can appear in a circular machine. Furthermore, the concept of periodic resonance crossing and its impact on the beam characteristics is discussed. In addition, some of the existing techniques for mitigations are presented. Finally, different ways of simulating the space charge effect are introduced.
