Development of a Compact Electron Beam Accelerator
Phone: (703) 250-1440
Microwave Technologies Incorporated is proposing the development of a very compact radio-frequency (rf) electron beam accelerator which appears to be well-suited for BMDO's directed energy applications. This novel concept employs a single short rf cavity operating in circular polarization to accelerate a low-energy ma ~netized pencil beam to energies that range from 2 to 10 MeV. The proposed accelerator produces a continuous high-energy high-current electron beam and should have numerous applications in industry and in medicine. Some examples include x-ray radiotherapy machines, electron beam welding, security x-ray imaging machines for airports, sterilization of medical waste and food processing. We propose a detailed non-linear analysis and multi-particle computer simulations of this concept in order to characterize maximum energy attainable, energy spectrum, beam-quality effects and other key parameters. Based on these studies, we will carry out a conceptual design in Phase I that should lead to the construction and testing of a prototype rf accelerator in Phase II. It is estimated that the proposed accelerator, due to its compactness and light weight, should provide a 50% reduction in the cost of the accelerator compared to conventional devices. If successful, this rf-acceleration scheme could be the basis for a new class of compact and affordable 2-10 MeV rf accelerators for radiotherapy and industrial applications. We anticipate that this compact rf-accelerator will be able to provide 2-10 MeV electron beams for applications such as radiotherapy, sterilization of medical waste, food processing and electron beam welding, among others. The proposed accelerator should be more compact, more affordable, and lighter in weis,ht than conventional small accelerators.
