SC niobium cavity technology (used for ILC) makes it possible to build a linear collider with energy recovery and multiple use of beams. To avoid parasitic collisions inside the linacs a twin LC is proposed. In this report, we consider the principle scheme of the collider, its energy consumption, and also estimate the achievable luminosity, which is limited by collision effects. With a duty cycle of 1/3, a luminosity of about 5x10³⁵ is possible, which is almost two orders of magnitude higher than at the ILC, where the beams are used only once. ER -
