Effects of the noise

In the following we collect general papers and presentations complementary to the one reported in the other sections, where we address a single and specific noise source.

As an example you can find, among other relevant papers, the description of the Lebedev noise model [1], the effect of the noise on the instability latency [2], the present implementation of the noise source in the emittance evolution model [3].
