Accelerating structure for a linear charged particle accelerator

摘要

An accelerating structure for a linear particle accelerator operating in the progressive wave mode or in the stationary wave mode and comprising at least one accelerating section and a complementary bunching or pre-accelerating section formed by a resonant cavity C of the "reentrant" type magnetically coupled with the first cavity of the accelerating section by means of a coupling iris, the cavity C having a length L=(2m+1) lambda o/4 and the distance D separating the interaction spaces of the cavity C and the first cavity of the accelerating section being equal to D=(2k+n/2+ alpha ) pi beta lambda o, with O
