Claim Text:
1. A method of generating a high dose rate of electrons of different energies using a traveling wave linear accelerator, the method comprising: coupling a first electromagnetic wave generated by a magnetron into the traveling wave linear accelerator; applying a first originating electron beam current to an electron gun to eject a first beam of electrons from the electron gun into the traveling wave linear accelerator, wherein the first beam of electrons has a first pulse length and is accelerated by the first electromagnetic wave to a first range of energies and output at a first captured electron beam current; coupling a second electromagnetic wave generated by the magnetron into the traveling wave linear accelerator; and applying a second originating electron beam current to the electron gun to eject a second beam of electrons from the electron gun into the traveling wave linear accelerator, wherein the second beam of electrons has a second pulse length that is different from the first pulse length and is accelerated by the second electromagnetic wave to a second range of energies and output at a second captured electron beam current, wherein a magnitude of the second captured electron beam current is different from a magnitude of the first captured electron beam current, wherein an energy output of the traveling wave linear accelerator is controlled by alternating between the first pulse length and the second pulse length and by further varying at least one of a) an originating electron beam current between the first originating electron beam current and the second originating electron beam current or b) a captured electron beam current between the first captured electron beam current and the second captured electron beam current, wherein a central value of the second range of energies is different from a central value of the first range of energies, and wherein the second range of energies and the first range of energies are interleaved.
