Abstract:
1. A traveling wave linear accelerator for generating a plurality of dose rates and energies of electrons, the traveling wave linear accelerator comprising: an electron gun modulator configured to adjust a pulse width and a beam injection time of a beam of electrons from an electron gun; a frequency/power controller configured to determine a frequency and a power of a radio frequency (RF) signal to be generated; and an intensity controller operatively associated with the electron gun modulator and the frequency/power controller, the intensity controller configured to receive a plurality of intensity/energy adjustment commands and to respectively determine a pulse width, a beam injection time, an RF power factor, and a frequency adjustment factor based on each intensity/energy adjustment command to provide a respective output dose rate and energy of electrons; wherein, for each intensity/energy adjustment command, the electron gun modulator receives the determined pulse width and the determined beam injection time and adjusts the pulse width and the beam injection time of the beam of electrons and the frequency/power controller receives the frequency adjustment factor and the RF power factor and adjusts the frequency and power of the RF signal such that the traveling wave linear accelerator generates electrons having the respective output dose rate and energy.
