Description

<p>A portable size and high energy X-ray source is produced by using the pyroelectric crystal. Energy and intensity of X-rays which it generates are evaluated. Three X-ray tubes with different condition and structure are produced using LiTaO3 single-crystalline that was a typical pyroelectric crystal. The highest X-ray energy generated by an X-ray tube was 80 keV with the power supply of 3 V and 1.2 A. A fluorescent X-ray spectrum of brass plate, which contains characteristic X-rays of Cu and Zn, is measured by using this X-ray tube. The characteristic X-rays analysis by exciting the sample with electrons is designed. When the brass plate is measured as a sample by using this method, characteristic X-rays of Zn is able to be confirmed clearly.</p>
