Abstract
An electron beam production and control assembly especially suitable for use in producing X-rays in a computed tomography X-ray scanning system is disclosed herein. In this system, an electron beam is ultimately directed onto an X-ray producing target in a converging manner using electromagnetic components to accomplish this. The system also includes an arrangement for neutralizing the converging beam in a controlled manner sufficient to cause it to converge to a greater extent than it otherwise would in the absence of controlled neutralization, whereby to provide ion aided focusing.
