Fe, Co, Ni, Cu, Mo, Ag, W,常用的是Cu靶。X射線管發(fā)生出來的不是純凈的單色光，包含多種波長的射線，主要的是K系射線。K系射線是指陰極電子碰撞陽極，使陽極電子產(chǎn)生K 激發(fā)，奧林巴斯Terra便攜式XRD分析儀哪里有，擊走K 層電子后，奧林巴斯Terra便攜式XRD分析儀哪里有，奧林巴斯Terra便攜式XRD分析儀哪里有，L層或M 層電子填充K

style="text-indent:25px">較大的傳統(tǒng)臺式XRD儀器一般不能使用對能量較為敏感的探測器，因此探測器會受到XRD實驗中未使用的光子的影響。相比之下，奧林巴斯的XRD分析儀可以去除那些未直接參與到X射線衍射實驗中的光子，如：X射線熒光光子，從而可以提供更好的信噪比模式。鈷射線管和銅射線管選項：奧林巴斯XRD分析儀的標(biāo)準配置裝配有一個堅固耐用的鈷（Co）靶材X射線管。這種陽極射線管廣受地質(zhì)學(xué)家和礦物學(xué)家的青睞，因為在分析鐵（Fe）含量較高的樣品時，這種射線管可以發(fā)揮出色的性能。不過，在某些應(yīng)用中（如：樣品中錳含量很高），需要使用銅（Cu）靶材X射線管。根據(jù)用戶具體應(yīng)用的需要，奧林巴斯可以提供這兩種陽極靶材X射線管的任何一種。X射線衍射儀是集光學(xué)、電學(xué)、機械傳動、水冷卻循環(huán)及計算機控制為一體的高精度復(fù)雜設(shè)備。</p><div
