METHOD AND DEVICE FOR IRRADIATING CONVERSION TARGET WITH ACCELERATED ELECTRONS CURRENT PULSES Russian patent published in 2005 - IPC

FIELD: nondestructive testing.

SUBSTANCE: method can be used for checking passenger's luggage and aviation and naval containers. Method concludes in generating electron beam in pulse forming unit. Current pulses are injected in structure accelerating electron beam. High-frequency pulses are generated inside the unit and passed to electron beam accelerating structure followed by bombardment of conversion target with flow of accelerated electrons. Accelerating structure operating in running wave mode is used as accelerating structure. Electron beam current pulse amplitude when generating in electron beam current pulse forming unit and values of high-frequency power pulse frequency in high-frequency power pulse forming unit are to be changed simultaneously. Device for irradiating conversion model has electron beam current pulse forming unit which has outputs connected with first input electron beam accelerating system through injector. Accelerating structure is made for bombarding conversion target with accelerated electron flow. Device also has high-frequency power pulse forming unit which has output connected with second input of electron beam accelerating system. Electron beam accelerating structure is made in form of accelerating structure operating at running wave mode. Electron beam current pulse forming unit has at least one synchronizer which has control output connected with control input of high-frequency power pulse forming unit. At least one synchronizer is made for simultaneous change of frequency of high-frequency power pulses at output of high-frequency pulse forming unit and value of change in electron beam current pulse amplitude at output electron beam current pulse forming unit.

EFFECT: improved degree of sensitivity relating to selection of material.
