This is done in terms of the concept of coupling impedance (both longitudinal and transverse) in full analogy with the conventional accelerators. It is shown that also here the coupling impedance is a very useful tool for the Nyquist-type stability analysis. Examples of specific physical situations are finally illustrated.
