摘要： These various embodiments serve to facilitate interlaced amplitude pulsing using a hard-tube type pulse generator having at least one energy-storage unit each comprising at least one energy-storing capacitor. Generally speaking, this comprises controlling an amount of energy withdrawn from the energy-storage unit and provided to an output load to form productive electric pulses by controlling at least one of: (1) energy replenishment; and (2) non-productive energy withdrawal of the energy-storage unit, to thereby achieve a series of productive interlaced amplitude electric pulses.

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.

摘要： Methods and apparatus involving neutron resonance radiography are used to map the elemental composition of an object. Neutrons are produced in a relatively broad band of energies from an efficient thick target whereby the angular dependence of the neutron energy can be used to scan multiple energies. Radial sectors of the neutron-emission spectrum having energies within particular energy bands are directed through an object rotated about the neutron source. The attenuation of the neutrons passed through the object is detected, and that data can be used to detect explosives, weapons, drugs, and other contraband.
