1. A radiation generation component comprising:
a high intensity target configured to produce Bremsstrahlung radiation with average dose rates of at least 40 greys per second (Gy/s) in response to impacts by charged particles as the high intensity target is moved laterally, the high intensity target including
a first Bremsstrahlung radiation zone configured to generate radiation in response to impacts by a first set of charged particles included in a first set of pulses of an electron beam,
a second Bremsstrahlung radiation zone configured to generate radiation in response to impacts by a second set of charged particles included in a second set of pulses of an electron beam, and
a third zone located laterally between the first Bremsstrahlung radiation zone and the second Bremsstrahlung radiation zone,
wherein the high intensity target has operating parameters used to determine operating limitations based on catastrophic failure mechanisms rather than fatigue failure mechanisms and the third zone is an air gap between the first Bremsstrahlung radiation zone and the second Bremsstrahlung radiation zone.
