Electron emission contributions to dark current and its relation to microscopic field enhancement and heating in accelerator structures

Electron emission contributions to dark current and its relation to microscopic field enhancement and heating in accelerator structures

Analytically tractable models of thermal-field emission, field enhancement, and heating mechanisms (Nottingham and resistive) are developed and combined to make estimates of the fields and temperatures that accompany the development and growth of asperities. The relation of asperity dimensions to da...
