摘要： A RF linear electron accelerator system for generating a beam of accelerated electrons bunched in pulses having different energy spectra from pulse to pulse. The system is operable to generate a beam of high energy X-rays from such beam of accelerated electrons, using a conversion target (225), with pulses of the X-ray beam (112) having energy spectra which are different from X-ray pulse to X-ray pulse. Preferably, the pulses of the electron beam (222) have energy spectra which alternate from pulse to pulse and, correspondingly, the pulses of the X-ray beam (112) have energy spectra which alternate from pulse to pulse. Also preferably, the current of electrons injected into the system's accelerating section (220) and the frequency of the pulse RF power supplied to the accelerating section (220) are changed in a synchronized manner to generate the electron beam (222). The system is employable in an inspection system (100) for discriminating materials present in containers by atomic numbers.

摘要： A radiographic inspection system for inspecting subject objects using charged particle beams having pulses of charged particles with different energy levels from pulse to pulse. A phase shifter (134) thereof enables adjustment of the RF power (106) delivered to first and second accelerating sections (102, 104) thereof from a single RF source without adjustment of the RF power generated by the RF source (130). The system also enables the generation of images of the contents of a container from multiple directions and in multiple planes, and allows the discrimination of materials present in the container.

摘要： A particle accelerator system, including apparatuses and methods, that is configurable through repositioning of shorting devices therein to operate at different charged particle beam currents while maintaining optimum transfer of electromagnetic power from electromagnetic waves to one or more accelerating sections thereof, and reducing or eliminating reflections of electromagnetic waves. The particle accelerator system includes at least two accelerating sections and an electromagnetic drive subsystem with portions of the electromagnetic drive subsystem being interposed physically between the accelerating sections, thereby making the particle accelerator system compact. The electromagnetic drive subsystem includes, among other components, a 3dB waveguide hybrid junction having a coupling window in a narrow wall thereof which is shared by the junction's rectangular-shaped waveguides. By virtue of the coupling window being positioned in a narrow wall rather than a wide wall, the maximal power of the 3dB waveguide hybrid junction is increased significantly.

摘要： A particle accelerator system for producing a charged particle beam having pulses of charged particles that have different energy levels from pulse to pulse. The system enables independent adjustment of the RF power delivered to first and second accelerating sections thereof without adjustment of the RF power generated by an RF source. Such independent adjustment enables the RF power provided to the first accelerating section to be maintained at a level appropriate for optimal particle capturing therein and for producing a tightly bunched beam of particles having different energy levels from pulse to pulse, while enabling the RF power provided to the second accelerating section to be varied in order to vary the energy levels of the charged particles of the charged particle beam from pulse to pulse.
