Cluster tip wavefront field emission cold cathode X-ray tube with counterpoint hole control strip

The invention relates to a cluster tip wavefront field emission cold cathode X-ray tube with a counterpoint hole control sheet, which comprises an anode combination body, a cathode combination body and a vacuum packaging shell, wherein the cathode combination body comprises a control sheet with counterpoint holes at the front end part, an emission sheet with a cluster tip wavefront field emission cold cathode close behind the control sheet, an insulating washer and an emission sheet lead-out conductor. In the invention, the traditional X-ray tube cathode heating circuit is omitted, and the controllable current of the cold cathode X-ray tube is realized; the problems of large size and difficult manufacturing of a high-insulation isolating transformer supplying power for a cathode lamp filament when the traditional hot emission cathode technology is adopted are avoided, so that X-ray radiation equipment with ultrahigh working voltage becomes light and small, the cost is lowered, the use is convenient and flexib
