Movable/replaceable high intensity target and multiple accelerator systems and methods

A radiation generation component comprising:

• a high intensity target configured to generate 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,
• said Bremsstrahlung radiation corresponds to peak dose rates greater than 0.001 Greys per pulse (Gy/pulse),
• the high intensity target is configured to be compatible with a radiation generation system,
• the high intensity target is configured to be loaded in the radiation generation system in under 5 minutes and unloaded from the radiation generation system in under 5 minutes, and
• the third zone is configured to prevent heat dissipation from the first Bremsstrahlung radiation zone from reaching the second Bremsstrahlung radiation zone in less than 1 millisecond.
