Accuray bases this proposal on an X-ray generator, model DX500K, designed, built, and delivered to a major contractor in December 2008 as part of the DNDO-CAARS program. Accuray`s DX500K operates at single or dual energy modes of 6 MeV and 9 MeV and interleaves between 6 MeV and 9 MeV at 400 Hz. The pulse to pulse jitter is negligible -- a major performance factor in high Z detection. The system operates in X-band making DX500K compact in size and weight. The strong progress of 6/9 MeV interleaved radiation as a means to detect high Z threat materials renders it a natural starting point for development of a 3/6/9 MeV interleaf system so that a single machine can accomplish multiple detection objectives in cargo inspection. We propose to use the DX500K as foundation to design a new system with energies 3, 6, and 9 MeV in single and interleaf modes. The repetition rate will be 800 Hz minimum with dose rates given in the technical proposal. Accuray has extensive experience in X-band accelerators. Our primary business in medical accelerators augments development of other applications via engineering, facilities and infrastructure and can easily transition to volume production
