Laser linear collider with a travelling laser focus supply

Requirements considered for 2×1 km long linac, driven by a laser radiation distributed within open accelerating structure with special sweeping devices. These devices deflect the laser radiation to the open accelerating structure in accordance with instant position of accelerated particles. The power reduction and shortening the time of illumination of every point of the structure is equal to the number of resolved spots, associated with the sweeping device. A 300 J, 100-ps laser flash could provide the energy 30 TeV for λ≅1 μm and 3 TeV for λ≅10 μm on 1 km with the method described. For repetition rate 160 Hz the luminosity associated with colliding beams could reach 10³³ cm^-2 s^-1 per bunch. Wall plug power required for operation of LLC is ~2 MW
