摘要： A linear accelerator comprises side-coupled cavity cells configured to accelerate electrons with a radio frequency field. The field amplitude in the initial cells is lower than in the later cells, and the initial cells are shorter than the later cells. This creates a capture section where electrons are captured and bunched while experiencing low acceleration, followed by an acceleration section where the bunched electrons experience stronger acceleration.

摘要： Methods and system for facilitating rapid radiation treatments are provided herein and relate in particular to radiation generation and delivery, electron source design, beam control and shaping/intensity-modulation. The methods and systems described herein are particularly advantageous when used with a compact high-gradient, very high energy electron (VHEE) accelerator and delivery system (and related processes) capable of treating patients from multiple beam directions with great speed, using all-electromagnetic or radiofrequency deflection steering is provided; or when used with a high-current electron accelerator system of energy range more conventionally used in photon radiation therapy to produce much faster delivery of intensity-modulated photon radiation therapy, that can in both cases deliver an entire dose or fraction of high-dose radiation therapy sufficiently fast to freeze physiologic motion, yet with a equal or better degree of dose conformity or sculpting compared to conventional photon therapy.

摘要： Multi-energy radiation sources comprising charged particle accelerators driven by power generators providing different RF powers to the accelerator, capable of interlaced operation, are disclosed. Automatic frequency control techniques are provided to match the frequency of RF power provided to the accelerator with the accelerator resonance frequency. In one example where the power generator is a mechanically tunable magnetron, an automatic frequency controller is provided to match the frequency of RF power pulses at one power to the accelerator resonance frequency when those RF power pulses are provided, and the magnetron is operated such that frequency shift in the magnetron at the other power at least partially matches the resonance frequency shift in the accelerator when those RF power pulses are provided. In other examples, when the power generator is a klystron or electrically tunable magnetron, separate automatic frequency controllers are provided for each RF power pulse. Methods and systems are disclosed.
