Abstract
Recently revealed values for the energy monochromaticity and exit aperture in the Schwarz‐Hora experiment are found to be inconsistent with the claimed beam current by orders of magnitude using the Langmuir brightness relation. Accordingly, attempts to duplicate the reported experimental conditions appear futile, and claims for the effect based upon the quoted experimental conditions may be regarded with skepticism.Keywords
