On-Chip Electron Beams for X-Ray Generation
Electron sources are core components in x-ray technologies. They are typically hot cathodes, which have critical limitations, including the inability to discriminate between materials, such as soft tissues and controlled substances. They also require significant heat management and power supplies to operate. To advance beyond these limitations, our patentpending, chip-based cold cathode sources are a necessary enabler of future imaging systems. Read more....
