Patent number: 11266006Abstract: Embodiments of the disclosed system and method provide for generating a multiple-energy X-ray pulse. A beam of electrons is generated with an electron gun and modulated prior to injection into an accelerating structure to achieve at least a first and second specified beam current amplitude over the course of respective beam current temporal profiles. A radio frequency field is applied to the accelerating structure with a specified RF field amplitude and a specified RF temporal profile. The first and second specified beam current amplitudes are injected serially, each after a specified delay, in such a manner as to achieve at least two distinct energies of electrons accelerated within the accelerating structure during a course of a single RF-pulse. The beam of electrons is accelerated by the radio frequency field within the accelerating structure to produce accelerated electrons which impinge upon a target for generating Bremsstrahlung X-rays.Type: GrantFiled: August 28, 2019Date of Patent: March 1, 2022Assignee: American Science and Engineering, Inc.Inventor: Aleksandr Saverskiy

Publication number: 20140192958Abstract: Methods and an x-ray system for dynamically regulating x-ray dose. An x-ray beam is generated and collimated at a source collimator and detected after the x-ray beam traverses an inspected object. A filter may be dynamically interposed by translation of the filter between a focal spot of the source and the source collimator in such a manner as to maintain the portion of the x-ray beam that traverses the inspected object below a specified limit. Alternatively, an aperture of the source collimator may be varied in size or position relative to the focal spot.Type: ApplicationFiled: January 2, 2014Publication date: July 10, 2014Applicant: American Science and Engineering, Inc.Inventors: Dan-Cristian Dinca, Martin Rommel, Seth Van Liew, Aleksandr Saverskiy

Patent number: 8457274Abstract: Methods and systems for x-ray inspection of an object using pulses whose spectral composition varies during the course of each pulse. A temporal sequence of pulses of penetrating radiation is generated such that the spectral content of each pulse evolves with time. The pulses are formed into a beam that is scanned across the object and detected after traversing the object. The detector signal is processed to derive at least one material characteristic of the object, such as effective atomic number, on the basis of temporal evolution of the detector signal during the course each pulse of the sequence of pulses. The time intervals may be predetermined, or else adapted based on features of the detected signal.Type: GrantFiled: October 17, 2011Date of Patent: June 4, 2013Assignee: American Science and Engineering, Inc.Inventors: Anatoli Arodzero, Martin Rommel, Aleksandr Saverskiy, Rajen Sud

Publication number: 20120093289Abstract: Methods and systems for x-ray inspection of an object using pulses whose spectral composition varies during the course of each pulse. A temporal sequence of pulses of penetrating radiation is generated, each pulse characterized by an onset and by a spectral content that evolves with time subsequent to the onset. The pulses are formed into a beam that is scanned across the object. The penetrating radiation from the beam that has traversed the object is detected, generating a detector signal. The detector signal is processed to derive at least one material characteristic of the object, such as effective atomic number, on the basis of temporal evolution of the detector signal during the course each pulse of the sequence of pulses. The detector signal is separately acquired for multiple time intervals relative to the pulse onset, and processed to obtain values corresponding to multiple-energy analysis of the transmitted radiation.Type: ApplicationFiled: October 17, 2011Publication date: April 19, 2012Applicant: AMERICAN SCIENCE AND ENGINEERING, INC.Inventors: Anatoli Arodzero, Martin Rommel, Aleksandr Saverskiy, Rajen Sud
