Patent number: 8339071Abstract: A particle accelerator system for producing a charged particle beam having pulses of charged particles that have different energy levels from pulse to pulse. The system enables independent adjustment of the RF power delivered to first and second accelerating sections thereof without adjustment of the RF power generated by an RF source. Such independent adjustment enables the RF power provided to the first accelerating section to be maintained at a level appropriate for optimal particle capturing therein and for producing a tightly bunched beam of particles having different energy levels from pulse to pulse, while enabling the RF power provided to the second accelerating section to be varied in order to vary the energy levels of the charged particles of the charged particle beam from pulse to pulse.Type: GrantFiled: March 19, 2007Date of Patent: December 25, 2012Assignee: ScanTech/IBS IP Holding Company, LLCInventors: Alexandre A. Zavadtsev, Gary F. Bowser

Patent number: 7491958Abstract: A radiographic inspection system for inspecting subject objects using charged particle beams having pulses of charged particles with different energy levels from pulse to pulse. A phase shifter thereof enables adjustment of the RF power delivered to first and second accelerating sections thereof from a single RF source without adjustment of the RF power generated by the RF source. The system also enables the generation of images of the contents of a container from multiple directions and in multiple planes, and allows the discrimination of materials present in the container.Type: GrantFiled: August 27, 2004Date of Patent: February 17, 2009Assignee: ScanTech Holdings, LLCInventors: Alexandre A. Zavadtsev, Gary F. Bowser

Publication number: 20080100236Abstract: A particle accelerator system, including apparatuses and methods, that is configurable through repositioning of shorting devices therein to operate at different charged particle beam currents while maintaining optimum transfer of electromagnetic power from electromagnetic waves to one or more accelerating sections thereof, and reducing or eliminating reflections of electromagnetic waves. The particle accelerator system includes at least two accelerating sections and an electromagnetic drive subsystem with portions of the electromagnetic drive subsystem being interposed physically between the accelerating sections, thereby making the particle accelerator system compact. The electromagnetic drive subsystem includes, among other components, a 3 dB waveguide hybrid junction having a coupling window in a narrow wall thereof which is shared by the junction's rectangular-shaped waveguides.Type: ApplicationFiled: March 19, 2007Publication date: May 1, 2008Applicant: ScanTech Holdings, LLCInventors: Alexandre A.
