UltraLo-1800超低本底α计数器

产品详情

       

      

UltraLO-1800超低本底α计数器用于低阿尔法材料(low Alpha)和极低阿尔法材料(Ultra low Alpha)的检测,检测材料的α辐射率,如半导体、微电子、集成电路等领域的晶圆片、焊接材料、封装材料、PCB材料等。基于其独特的内部结构设计和强大的算法,可以有效的识别和区分α测量中的有效信号和设备本底信号,并在处理数据时将本底信号直接去除,相当于达到等效本底0.0001 alpha/cm2/hr甚至更低,进而极大的缩短测量时间(可在10小时内完成0.001-0.0005 alpha/cm2/hr辐射率材料的检测;在100小时内完成小于0.0005 alpha/cm2/hr辐射率材料的检测)。

UltraLO-1800也可用于物理研究中的“罕见事件”测量和环保相关的研究。
