Cluster tip wavefront field emission cold cathode X-ray tube with registration hole control sheet

The utility model relates to a cluster tip wavefront field emission cold cathode X-ray tube with a registration hole control sheet. The cluster tip array plane field emission cold cathode X-ray tube comprises an anode combination, a cathode combination and a vacuum packaged casing, wherein the cathode combination is composed of the control sheet with the front end provided with a registration hole, a field emission cold cathode X-ray sheet provided with a cluster tip array plane and closely arranged at the back of the control sheet, an insulation washer and an emission sheet leading-out lead. The cluster tip wavefront field emission cold cathode X-ray tube omits the traditional X-ray tube cathode heating circuit and achieves cold cathode X-ray tube current controllability; and solves the problems of large volume and manufacture difficulty of a high-insulation isolation transformer for supplying electricity to a cathode filament by aid of the traditional heat emission cathode technology, enables an ultrahigh w
