ALTERNATIVE CONCEPT OF AN RF POWER-SUPPLY FOR TEV LINEAR COLLIDERS

A novel concept of an rf power supply for TeV linear colliders is prop osed. The rf power source consists of a large number of low-power ampl ifiers commutated into a phased array antenna. This electronically sca nned array transmits rf power through the air to the receiving array w hich feeds accelerating structures and is located in the vicinity of a n accelerator. Such an approach, using serial rf amplifiers and well d eveloped phased array antenna technique, enables one to decrease the r equired peak rf power by three orders of magnitude with respect to the traditional approach and, furthermore, to increase the overall reliab ility of the rf system.
