	ThomX Compact X ray source is a 50 MeV storage ring, and a linear accelerator based on a photo-injector. As the electron beam in the ring will not be damped by synchrotron radiation, the transfer line should rely on a precise injection in the ring. In order to fulfill this requirement, especially in terms of optics function and orbit correction, different tools have been prepared and tested on the accelerator toolbox of Matlab Middle Layer. We will present the different tools and the underlying physics for the ThomX transfer line.

	The THOMX facility is a compact X-Ray source based on the Compton back scattering aiming at a flux of 10¹¹ to 1013 ph/s in the range of energy from 40 to 90 keV. Due to the compactness and the expected stability of this machine, high requirements are set for all magnets in terms of design and manufacturing. First, the design optimization of the magnets is presented, leading to high performance in terms of harmonics. Issues regarding the cross-talk between quadrupole and sextupole fields are then discussed.

	ThomX Compton light source is designed to maximise the average X-ray flux providing a compact and tunable machine which can operate in hospitals or in museums. These constraints impose the choice of a high collision rate which is based on S-band Linac whose energy is 50-70 MeV combined to an electron storage ring. As most of the performances of the electron beam at the interaction point depend on the beam quality at the ring entrance, the linear accelerator must be carefully designed and especially the photo-injector. Simulations have been carried out in order to optimise the emittance for the ring entrance. Indeed, for a bunch charge of 1 nC, space charge effects usually dominate the total beam emittance. The latter can be minimized at the end of the Linac by means of emittance compensation. The best configuration across all the parameters will be presented.

ThomX Compton light source is designed to maximise the average X-ray flux providing a compact and tunable machine which can operate in hospitals or in museums.

As most of the performances of the electron beam at the interaction point depend on the beam quality at the ring entrance, the linear accelerator must be carefully designed and especially the photo-injector.
