    Abstract: A compact and low-cost electromagnetic wave generator in which X-rays having high intensity can be generated and the energy of generated X-rays can rapidly be switched. In an electromagnetic wave generator including a circular accelerator, a deflection electromagnet incorporated in the circular accelerator focuses injected and accelerated electrons. The circular accelerator produces stable closed electron orbits in respective regions with respective widths in the radial direction of the accelerator. The closed electron orbits are stable during injection and acceleration of electrons. A target is arranged across only some of the stable closed electron orbits so that a collision region, where a circulating electron beam collides with the target, and a non-collision region, where a circulating electron beam does not collide with the target, are produced. Through control of respective patterns of changes with time of the deflection magnetic field, a given electron closed orbit is shifted between the collision and the non-collision regions, thereby generating X-rays.

    Abstract: An X-ray generator capable of reliably reducing an X-ray focal spot size without depending on the focal spot size of an electron beam on a target. Providing, within the irradiation range of an electron beam B of a target laminated structure 3 comprising a target 2 and an X-ray irradiation window 1, a low X-ray absorptivity region 3a of localized low X-ray absorptivity in the irradiation direction of the electron beam B results in the suppression of emission to the outside of X-rays from among the X-rays generated as a result of the irradiation of the electron beam B onto the target 2 that are from regions other than the low X-ray absorptivity region 3a, and an X-ray focal spot of a size corresponding to the size of the low X-ray absorptivity region 3a is obtained regardless of the size of the irradiation region of the electron beam B.

    Abstract: Multi-energy radiation sources comprising charged particle accelerators driven by power generators providing different RF powers to the accelerator, capable of interlaced operation, are disclosed. Automatic frequency control techniques are provided to match the frequency of RF power provided to the accelerator with the accelerator resonance frequency. In one example where the power generator is a mechanically tunable magnetron, an automatic frequency controller is provided to match the frequency of RF power pulses at one power to the accelerator resonance frequency when those RF power pulses are provided, and the magnetron is operated such that frequency shift in the magnetron at the other power at least partially matches the resonance frequency shift in the accelerator when those RF power pulses are provided. In other examples, when the power generator is a klystron or electrically tunable magnetron, separate automatic frequency controllers are provided for each RF power pulse. Methods and systems are disclosed.

    Abstract: One or more components of an x-ray target assembly are manufactured using an electroforming process. The electroforming is carried out by providing an electroforming apparatus that includes an electrolyte, a metal anode, and an electrically conductive cathode. The cathode includes an intermediate x-ray target assembly upon which the metal is to be deposited and/or an electrically conductive mold for forming a component of an x-ray target assembly. The x-ray target component (e.g., a substrate or focal track) is formed by submersing the cathode in the electrolyte and applying a voltage across the anode and the cathode to cause the metal from the anode to be electroformed on the intermediate target and/or the mold. The electroforming is continued until a desired thickness of metal is achieved. The electroforming process can be used to manufacture an x-ray target substrate, focal track, stem, barrier, or other metal layer of the target assembly.
