为提高分析测量241Amα能谱的速度,设计了一种能装入30个样品的真空样品室。大批量测量时,影响测量速度的主要因素是样品更换与抽真空过程。为此,将真空室分为上下两层,在尽量缩小真空室体积情况下,每批可装30个待测样品。为方便换样,又满足密封要求,将样品盘设计成10个独立环 In order to improve the speed of analyzing and measuring 241Amα spectrum, a vacuum sample chamber capable of loading 30 samples was designed. When measuring in large quantities, the main factors that affect the measurement speed are the sample change and evacuation process. To this end, the vacuum chamber is divided into two layers, in the case of minimizing the volume of the vacuum chamber, each batch can hold 30 samples to be tested. To facilitate sample change, but also to meet the sealing requirements, the sample tray designed into 10 independent rings
