Abstract
The vacuum-sealed miniature modulated x-ray source (VMMXS) with a hot cathode is
fabricated via the single-step brazing process in a vacuum furnace. An experiment
following the VMMXS is implemented to present its performances, including the influence
of grid electrode potential on x-ray intensities. The modulation type of the grid
electrode as a switch is proposed, and its feasibility is successfully demonstrated. It
is noteworthy to discover a phenomenon for the first time, to the best of our knowledge,
that the high repetition frequency grid pulse of the VMMXS has a significant effect on
the x-ray intensity. The probable cause for this new finding is analyzed.
