Provided are an X-ray generator capable of easily measuring a beam size of an electron beam on an electron target, and an adjustment method therefor. The X-ray generator includes an electron target including a first metal, a second metal different from the first metal, and a third metal different from the second metal, which are sequentially arranged side by side along a first direction in a continuous manner.

X-ray generator and adjustment method therefor

A coolant passage is formed inside the rotary shaft while an air passage is formed inside the casing. A mechanical seal is arranged between the coolant passage and the air passage. Leakage cooling water, which has leaked in the form of vapor from the mechanical seal, is relegated radially outwardly along with air by the action of a rotary vane, which is disposed in the air passage, and finally flows out of an air outlet. A coolant sensor may be provided to early detect the leakage water.
