摘要： PROBLEM TO BE SOLVED: To prevent discharge between a glass tube housing a cold cathode element and a housing located at the outer side of the glass tube thereby extending lives of the cold cathode element and the X ray generator compared to conventional X ray generators and realizing the stable operations in the X ray generator using the field emission type cold cathode element.SOLUTION: A housing 2 is grounded. A cold cathode element 5, which is subject to a voltage applied from a direct current power source 7 to discharge electrons, is housed in a glass tube 4, and a lower end part 4a of the glass tube 4 is supported by an insulation material 3 in the housing 2. A target 8 and a window part 9 discharging X rays generated by the target 8 to the exterior part are provided at the upper end part side of the glass tube 4. A peripheral part 4b of the lower end part 4a in the glass tube 4 is covered by the insulation material 3 and a surface of the insulation material 3 is covered by a grounded conductor.

摘要： PROBLEM TO BE SOLVED: To obtain a long life field emission type X-ray generator without using any special electron emission element.SOLUTION: A field emission type X-ray generator 10 includes a cold-electrode 12 which becomes an electron emission element. A negative voltage of several tens of kV is applied to the cold-electrode 12 from a DC power supply 21 via a high voltage cable 22. In addition to a first current control resistor 31 provided near the DC power supply 21, a second current control resistor 41 is provided near the cold-electrode 12. Even if an overcurrent due to the parasitic inductance L or capacitance C of the high voltage cable 22 is generated and begins to flow into the cold-electrode 12, the overcurrent can be prevented from flowing, as it is, into the cold-electrode 12 by the second current control resistor 41 and thereby long life of the cold-electrode 12 is ensured.
