Patent ID: 7208890

Claim:
A particle accelerator comprising: an injector for generating charged particles; an electromagnetic drive subsystem for generating pulses of electromagnetic waves; a first accelerating section adapted to receive said electromagnetic waves and to transfer energy from said electromagnetic waves to said charged particles as said charged particles travel therethrough; a second accelerating section adapted to transfer energy to said charged particles as said charged particles travel therethrough; a waveguide connected to said electromagnetic drive subsystem and adapted to deliver said electromagnetic waves from said electromagnetic drive subsystem to said first accelerating section, said waveguide having a wall at least partially physically interposed between said first accelerating section and said second accelerating section; a 3 dB waveguide hybrid junction formed at least partially from said wall, said 3 dB waveguide hybrid junction defining a coupling window in said wall; and a tube connected to and extending between said first accelerating section and said second accelerating section, said tube being adapted to enable said charged particles to travel between said first accelerating section and said second accelerating section.
