Interlaced multi-energy radiation sources

Use of automatic frequency tuning devices is provided to match the frequency of RF power provided to an accelerator with the accelerator resonance frequency. In one version, where the RF power pulse generator is a mechanically tunable magnetron, automatic frequency tuning is provided to match the frequency of RF power pulses at one power level 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 supply power level at least partially matches the resonance frequency shift in the accelerator when those RF power pulses are provided. In other versions, when the RF power pulse generator is a klystron or electrically tunable magnetron, a separate automatic frequency tuning device is provided for each power level of the RF pulses.

Linear inductive accelerator

Linear inductive accelerator contains inductive system in form of a set of ferromagnetic cores, enveloped by magnetization coils. On both sides of cores outputs of magnetization coils are electrically combined and connected to outputs of last compression unit of impulse generator. Magnetic impulse generator is a series of at least two compression units, consisting of capacitors and saturation throttles. In parallel to the last compression unit of magnetic impulse generator, additional compression units are connected. Generation of high voltage impulse by inductive system is performed due to serial discharge of capacitors of compression units through windings of saturation throttles onto magnetization coils of inductive system. Delay of impulse feeding from additional compression units into inductive system is achieved by using saturation throttles with varying interlinkage values.

Accelerator having high-frequency power source

Accelerator provided with high frequency power source includes ferrite circulator; magnetron connected to first branch of ferrite circulator; first resonator accelerating section connected to second branch of ferrite circulator; load connected to third branch of ferrite circulator; second resonator accelerating section connected to fourth branch of ferrite circulator. The last is provided with solenoid supplied from pulse-type variable-polarity current source. Each accelerating section is tuned for optimal acceleration of particles up to predetermined energy value.
