Field emission is at the heart of a wide range of research areas
and technologies. The commercialisation of some of these
technologies has been limited due to the challenges to achieve
emission uniformity, yield, and lifetime within the tolerances
that the industry demands. The recent advances in simulation
tools and nanofabrication have enabled the effective design and
production of field emitter...
The need for a low-cost, low-dose 3D imaging capability, as an alternative to CT and MRI scanners, has driven the development of a multi-cathode, stationary Digital Tomosynthesis (s-DT) scanner. Demonstration experiments with an array of cold cathodes as electron sources have been reported by multiple groups. We report the operation of a device with a different field emitter geometry, at 60kV, to...
