초록

엑스선 회절분석기는 비파괴적인 방법으로 시료의 정보를 정성 및 정량적으로 분석할 수 있다. 엑스선 회절분석기에는 다양한 광학소자가 사용된다. 평행빔 광학소자는 광축에 평행한 빔을 통과시키고 발산하는 빔을 제거하는 역할을 한다. 와이어 컷 제작과 스테인리스 스틸 평판을 연마하여 평행빔 광학소자를 제작하였고 엑스선 영상장치를 이용하여 그 평행도를 평가하였다. 설계된 6 mrad과 매우 가까운 6.6 mrad의 평행도를 갖는 평행빔 광학소자를 제작하였다. 엑스선 영상을 이용하면 개개의 평판의 평행도를 예측할 수 있을 뿐만 아니라 다양한 광학소자 평가에도 사용될 수 있을 것이다.

An X-ray diffractometer which has various X-ray optics can give qualitative and quantitative information for a sample using a nondestructive analysis method. A parallel beam optic passes the parallel beam and removes divergent beam generated from an X-ray tube. The parallel beam optic used in the X-ray diffractometer was fabricated by wire cut and grading of stainless steel plates and was evaluated its performance using an X-ray imaging system. The measured parallelization of 6.6 mrad for the fabricated the parallel beam optic was a very close to the expected value of 6 mrad. An X-ray imaging technique for evaluating the parallel beam optics can estimate parallelization for each plate and can be used to other X-ray optics.
