Abstract
The disclosure relates to systems and methods for fast-switching operating of a standing wave linear accelerator (LINAC) for use in generating x-rays of at least two different energy ranges with advantageously low heating of electronic switches. In certain embodiments, the heating of electronic switches during a fast-switching operation of the LINAC can be kept advantageously low through the controlled, timed activation of multiple electronic switches located in respective side cavities of the standing wave LINAC, or through the use of a modified a side cavity that includes an electronic switch.
