Abstract: The disclosure relates to systems and methods for interleaving operation of a standing wave linear accelerator (LINAC) for use in providing electrons of at least two different energy ranges, which can be contacted with x-ray targets to generate x-rays of at least two different energy ranges. The LINAC can be operated to output electrons at different energies by varying the power of the electromagnetic wave input to the LINAC, or by using a detunable side cavity which includes an activatable window.

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.

Abstract: A dual-plunger energy switch assembly for standing wave linear particle beam accelerators capable of operating in a higher energy mode and a lower energy mode employs two mechanical plungers that can be extended different distances inside two side cavities of the linear accelerator. When the linear accelerator is operated in the higher energy mode, both plungers are retracted out of the side cavities. To achieve high output while the linear accelerator is operated in the lower energy mode, the two plungers are radially inserted into the two side cavities to adjust the electromagnetic accelerating field along the length of the accelerator, e.g., one plunger is inserted into a side cavity so that the plunger touches the smile surface of the side cavity, while the second plunger is inserted into a second side cavity so that the plunger is adjacent to, but not touching, the smile surface of the side cavity.
