Description
焦電結晶を用いてポータブルサイズかつ高エネルギーのX線源を製作し,発生するX線のエネルギーおよび時間当たりのX線強度を評価した.代表的な焦電結晶であるLiTaO3 単結晶を用い,条件や構造を変えて3つのX 線管を製作した.最も高いエネルギーのX線まで発生したさせたX線管では,これまでのところ3 V,1.2 Aの電源で80 keV 程度までのエネルギーのX 線が確認できた.また,この線源を用いて真鍮板の蛍光X 線スペクトルを測定し,Cu とZn の特性X線を確認できた.さらに試料を電子により励起することにより特性X線分析を考案した.この方法と蛍光X線分析を,真鍮板を試料として比較した結果,ZnのKβ線のピークをよりはっきり確認することができた.
Description Alternative
 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.
