One ad­van­tage of X-ray sources based on Comp­ton Back Scat­ter­ing (CBS) pro­cess­es is that such com­pact ma­chines can pro­duce an in­tense flux of monochro­mat­ic X-rays. CBS re­sults from col­li­sions be­tween laser puls­es and rel­a­tivis­tic elec­tron bunch­es. Aim­ing at high X-ray flux, one pos­si­ble con­fig­u­ra­tion com­bin­ing a low emit­tance lin­ear ac­cel­er­a­tor with a com­pact stor­age ring and a high gain laser cav­i­ty has been adopt­ed by the ThomX pro­ject. We pre­sent here the main ring lat­tice char­ac­ter­is­tics in terms of base­line op­tics, pos­si­ble other tun­ings such as low or neg­a­tive mo­men­tum com­paction, and orbit cor­rec­tion schemes. In ad­di­tion, non-lin­ear beam dy­nam­ics as­pects in­clud­ing fringe field com­po­nents as well as high­er mul­ti­pole tol­er­ances are pre­sent­ed.
