SPARC and SPARX are two different initiatives toward an Italian Free Electron Laser (FEL) source operating in the Self Amplified Spontaneous Emission (SASE) mode, in which several national research institutions are involved. SPARC is a high gain FEL project devoted to provide a source of visible and VUV radiation while exploiting the SASE mechanism. An advanced Photo-Injector system, emittance compensating RF-gun plus a 150 MeV Linac, will inject a high quality e-beam into the undulator to generate high brilliance FEL radiation in the visible region at the fundamental wavelength, (∼500 nm). The production of flat top drive laser beams, high peak current bunches, and emittance compensation scheme will be investigated together with the generation of higher harmonic radiation in the VUV region. SPARX is the direct evolution of such a high gain SASE FEL toward the 13.5 and 1.5 nm operating wavelengths, at 2.5 GeV. To get the required value for the bunch peak current, Ipeak ≈ 2.5 kA, the “hybrid” scheme, RF-compression stage plus magnetic chicane, is analyzed and compared with the more standard double stage of magnetic compression. The two options are reviewed considering the tolerance to the drive laser pulse phase jitter.

Summary
Introduction
The consideration of multiplicative or colored noise in nonlinear dynamical systems has revealed a wide zoology of interesting phenomena (see, e.g., Graham and Schenzle, 1982; Hänggi, 1986; Horsthemke and Lefever, 1984; Sancho, San Miguel, Katz and Gunton, 1982; San Miguel and Sancho, 1981; Schenzle and Brand, 1979; Smythe, Moss and McClintock, 1983) which are well beyond the basic and classic picture that emerges from the linearized treatment (Van Kampen, 1961). In the framework of nonlinear systems, under special conditions, the presence of noise can give rise to striking qualitative deviations from the deterministic (i.e. noiseless) picture even for rather low noise levels (Broggi, Lugiato and Colombo, 1985). Furthermore, in the nonlinear domain a multiplicative noise or a colored noise can determine a behavior qualitatively different from that which arises from additive white noise; in some examples, these differences persist even in the small noise limit (Lugiato, Broggi and Colombo, 1986; Lugiato, Colombo, Broggi and Horowicz, 1986).
Modern optics provides a very appropriate framework to study not only nonlinear phenomena, but also noise effects. In fact, the theoretician can describe the behavior of optical systems by means of relatively simple models, that nonetheless are sufficiently realistic to allow a comparison with experimental data. On the other hand, in the field of optics it is possible to realize experiments on noise that allow a degree of control to some extent comparable to that attainable in analogous electronic experiments; an example is the observation of transient optical bimodality in optically pumped sodium vapor (Lange, Mitsche, Deserno and Mlynek, 1985; Mitsche, Deserno, Mlynek and Lange, 1985).
