Claim Text:
1. A standing wave electron linear accelerating apparatus comprising: an electron gun configured to generate electron beams; a pulse power source configured to provide a primary pulse power signal; a power divider coupled downstream from the pulse power source and configured to divide the primary pulse power signal outputted from the pulse power source into a first pulse power signal and a second pulse power signal; a first accelerating tube arranged downstream from the electron gun, coupled to the power divider and configured to accelerate the electron beams with the first pulse power signal; a second accelerating tube arranged downstream from the first accelerating tube, and configured to receive the second pulse power signal from the power divider and accelerate the electron beams with the second pulse power signal; a phase shifter coupled to an output of the power divider and configured to continuously adjust a phase difference between the first pulse power signal and the second pulse power signal so as to generate accelerated electron beams with continuously adjustable energy at an output of the second accelerating tube; and a target arranged downstream from the second accelerating tube and configured to be hit by the accelerated electron beams to generate X-rays; wherein the target is mounted on a rotatable base so that an angle of an incident direction of the accelerated electron beams with respect to a surface of the target varies with the energy of the electron beams; wherein the target is mounted in a vacuum box that is fixed on the rotatable base, wherein the side of the vacuum box includes an X-ray window and the second accelerating tube is coupled to the vacuum box via a corrugated pipe.
