Microfocus X-ray generators presently use a tungsten filament as the source of electrons. This has a large size and limited life. A field emission source has a very small size and a long life. This project investigates the feasibility of using a field emission source in a microfocus X-ray generator.

Phase II

Contract Number: F33615-91-C-5658

This proposal would build a test microfocus X-ray generator using the high brightness electron source which was tested in Phase I. This will be used to test the operation and parameters of the high brightness source in a working microfocus X-ray source. We expect this to produce a prototype X-ray generator capable of focussing many more electrons into a microfocus spot. This cathode will also be significantly more stable and have a longer life. As a consequence of the improved performance the prototype generator will be built to operate at a higher energy and beam current than present generators.
