The utility model discloses a ripple glass bulb X -ray tube, including glass shell, cathode assembly and positive pole subassembly, the surface of glass shell is equipped with corrugated column structure. The utility model discloses a corrugate glass bulb has longer glass bulb along face length degree under certain homogeneous tube size, littleer glass bulb along a face electric potential gradient can increase the creepage degree of difficulty of glass bulb stored charge under littleer homogeneous tube size, improve the withstand voltage level of homogeneous tube, adapts to the requirement of superhigh pressure to become the superhigh pressure X -ray tube.
