摘要
A transmission type micro-focus X-ray generation apparatus includes an electron reflector, an electron passage surrounded by the electron reflector, an electron source, and a target. X-rays are generated by irradiating the target with electrons that have been emitted from the electron source and that have passed through the electron passage. The electron passage has a conical shape having a cross-sectional area that increases from an outlet on the target side toward an inlet on the electron source side. A material of the target is molybdenum, tantalum, or tungsten. The atomic number of a material of the electron reflector is greater than or equal to the atomic number of the material of the target.
