  Two-stream instability at soft X-ray wavelengths for increasing brightness of Compton sources. We propose a novel scheme which may result in the next generation Compton source for soft X-rays. The scheme is based on creating an electron beam distribution consisting of several energy bands and allowing for the two-stream instability to develop resulting in a short scale density modulation. The multi-stream beam distribution is created within a single bunch through EEHG mechanism which results in well separated bands with close energies. The wavelength of the microbunching caused by the two-stream instability strongly depends on the beam parameters and can be reduced down to soft X-ray wavelengths that are not achievable with other mechanisms. The microbunching can be used for
