The need of a fs-scale pulsed, high repetition rate, X-ray source for time-resolved fine analysis of matter
(spectroscopy and photon scattering) in the linear response regime is addressed by the conceptual design of a
facility called MariX (Multi-disciplinary Advanced Research Infrastructure for the generation and application of
X-rays) outperforming current X-ray sources for the declared scope. MariX is based on the original design of a
two-pass two-way superconducting linear electron accelerator, equipped with an arc compressor, to be operated

THz radiation is one of the most appealing portion of the electromagnetic spectrum in terms of multi-disciplinary use in basic science and technology. Beyond the numerous applications, a great interest is its potential for future, compact linear accelerators. Conventional radio-frequency accelerating structures operating at the S and C band can reach gradients up to 30 - 50MV/m, respectively; higher accelerating gradients, of the order of 100MV/m, have been obtained with X-band cavities.
