ELECTRON EMISSION DEVICE AND X-RAY GENERATOR INCLUDING THE SAME

摘要

PURPOSE: An electron emitting device and an X-ray generating device prevent the loss of the device due to arcing by preventing electric charges from being charged in insulating materials. CONSTITUTION: A gate electrode of a mesh structure is separated from a cathode electrode (11). Multiple gate spacers (12) are arranged between the cathode electrode and the gate electrode. Multiple electron emission sources (15) are alternately arranged with one among the multiple gate spacers between the cathode electrode and the gate electrode.
