Accelerator system stabilization for charged particle acceleration and radiation beam generation

摘要

A method for generating stabilized particle acceleration by a radio-frequency (RF) accelerator is described, comprising operating the accelerator in a warm-up mode during a warm-up time period, without injecting charged particles or without accelerating injected charged particles, and operating the accelerator in a beam-on mode during a beam-on time period after the warm-up time period, to accelerate charged particles injected by the charged particle source. Automatic frequency control to match an expected frequency of the accelerator during the beam-on time period, prior to the start of the beam-on time period, for stability, is also described.

1. A stabilized radio-frequency (“RF”) accelerator system, comprising:
an RF accelerator to accelerate charged particles; an RF source coupled to the accelerator to provide RF power into the accelerator; a charged particle source coupled to the accelerator to inject charged particles into the accelerator; at least one high voltage electric power supply coupled to the RF source and the charged particle source to provide electric power thereto; at least one controller configured to: cause supply of high voltage electric power from the at least one high voltage electric power supply to at least one of the RF source or the charged particle source without accelerating charged particles injected by the charged particle source, during a warm-up time period; and cause supply of high voltage electric power from the at least one high voltage electric power supply to the RF source and to the charged particle source during at least partially overlapping times, to accelerate charged particles injected by the charged particle source, during a beam-on time period.
