Schottky-Enabled Photoemission and Dark Current Measurements-Toward an Alternate Approach to Fowler-Nordheim Plot Analysis

Field-emitted dark current, a major gradient-limiting factor in RF cavities, is usually analyzed via FowlerNordheim (FN) plots. Traditionally, field emission is attributed to geometrical perturbations on the bulk surface whosefield enhancement factor (beta) and the emitting area (A) can be extracted f...
