The present invention is directed toward an X-ray scanning system having a plurality of detectors and a controller, where a) the controller is configured to receive and identify a minimum X-ray transmission level detected by at least one detector, b) the controller compares the minimum X-ray transmission level to at least one predetermined threshold transmission level, and c) based on said comparison, the controller generates an adjustment signal. The present invention further comprises an X-ray source, where the X-ray source receives an adjustment signal and is configured to adjust an X-ray pulse duration based on the adjustment signal.

A control apparatus for controlling RF power supplied to first and second loads is provided. The control apparatus includes a first symmetric hybrid junction having a first port for receiving input RF power, a second port coupled to the first load and a third port coupled to a dummy load. The control apparatus further includes a second symmetric hybrid junction having a first port coupled to a fourth port of the first symmetric hybrid junction and a third port coupled to the second load. First and second variable shorts are respectively coupled to second and fourth ports of the second symmetric hybrid junction. RF power reflected by the first and second variable shorts is controllably directed through the second symmetric hybrid junction to the second load. The amplitude and phase of the RF power supplied to the second load can be controlled independently. In a preferred embodiment, the first and second loads are first and second accelerator guide sections of a linear accelerator, and the control apparatus is used to control the output beam energy of the linear accelerator.

A linear accelerator for charged particles includes a plurality of accelerating stages in a linear arrangement along a central axis. Each accelerating stage has at least one passageway radially spaced from the central axis for transmitting a beam of charged particles. Electromagnetic wave energy is coupled to the accelerating stages to produce an accelerating electric field in a region of the passageway of each of the accelerating stages. Coupling circuits couple the electromagnetic wave energy between adjacent accelerating stages. Each accelerating stage may be configured as an annular accelerating cavity or as two or more accelerating cavities disposed around the central axis. The passageway may be configured as two or more discrete apertures or a single annular aperture. Beam bending devices may be used to direct the charged particle beam through the accelerator two or more times. The linear accelerator produces a high current, high energy charged particle beam.

An RF linear accelerator using CW or low amplitude pulsed RF excitation which can efficiently accelerate charged particles from 0. 1 C to relativistic velocities in excess of 0. 9 C. A charged particle source feeds charged particles having velocities of about 0. 1 C into a first type RF LINAC having a plurality of side coupled resonator cavities each having a drift tube in the middle. The RF length of the cavities is set relative to the velocity of the particles and the RF excitation wavelength such that the particles experience in-phase accelerating E fields in the gaps on either side of the drift tube and are shielded from decelerating E fields while inside the drift tubes. The RF coupling cavities establish sufficient phase change between adjacent resonators such that the particles arrive in the adjacent resonator cavities in synchronization with oscillations in the standing wave therein so as to experience further acceleration. The first RF LINAC accelerates the particles to 0. 5 C approximately.
