RADIATION GENERATING TUBE, RADIATION GENERATING DEVICE USING THE SAME, AND RADIOGRAPHY SYSTEM

摘要

PROBLEM TO BE SOLVED: To provide a radiation generating tube with high pressure resistance reliability in which discharge caused by foreign matter is reduced.SOLUTION: By disposing a conductive container 5 having an opening 5a in a radiation generating tube 1 and disposing a dielectric substance 7 in the conductive container 5, foreign matter incident to the conductive container 5 from the opening 5a is captured by the dielectric substance 7.
