加速器质谱（AMS）是用于测量长寿命锕系元素的超灵敏技术，例如，236 U、237 Np和Pu同位素。为了提高锕系元素丰度的检测限，提高锕系元素AMS测量的检测效率，意大利卡塞塔文化与环境遗产同位素研究中心采用16条硅探测器对锕系元素进行了鉴定。236 U/238 U的灵敏度为1 × 10 - 11（空间分辨率）和5.0 × 10 - 12（时间分辨率）。本文报道了17.26MeV低能区离子注入硅探测器中~（236）U的脉冲高度缺陷。
Accelerator mass spectrometry (AMS) is an ultrasensitive technique for measuring long-lived actinides, e.g.,236U,237Np and Pu isotopes. In order to improve the detection limit for actinides abundance, and to increase the detection efficiency in actinides AMS measurement, a 16-strip silicon detector was used to identify actinides at the Center for Isotopic Research on Cultural and Environmental heritage in Caserta, Italy. The sensitivity of236U/238U was 1 × 10−11by special resolution and 5.0 × 10−12by time resolution. The pulse height defect of236U in an ion-implanted silicon detector in the low-energy range with 17.26 MeV is presented.
