Abstract

The 1 MV multi-element AMS system at Beijing Normal University, built by High Voltage Engineering Europa B.V., is now commissioned after some delay. This advanced 1 MV system is uniquely configured to accommodate low background analyses of all elements from tritium to actinides, including an additional detector line dedicated to beryllium ion detection with improved overall ion transmission efficiency. For the main detector line, both the low- and high-energy magnet chambers are electrically insulated so that a rapid sequential isotope selection mode can be used for measuring actinide isotopes at ∼ 1 Hz cycling rate. In this report, data covering ¹⁰Be, ¹⁴C, ²⁶Al, ⁴¹Ca, ¹²⁹I, ^239,240Pu and ²³⁶U from the recently completed on-site acceptance tests are presented. The initial experiences with routine radiocarbon analyses are also reported.

满配1mv BNU-AMS系统调试报告

北京师范大学由欧罗巴高压工程公司建造的1毫伏多单元AMS系统，经过一段时间的延迟，现在已经投入使用。这种先进的1 MV系统具有独特的配置，可适应从氚到锕系元素的所有元素的低背景分析，包括一个专门用于铍离子检测的额外探测器线，提高了整体离子传输效率。对于主探测器线路，低磁室和高能磁室都是电绝缘的，因此可以使用快速顺序同位素选择模式以~ 1 Hz循环速率测量锕系元素同位素。本报告提供了最近完成的现场验收试验的10Be、14C、26Al、41Ca、129I、239,240Pu和236U的数据。还报告了常规放射性碳分析的初步经验。

期刊介绍： Section B of Nuclear Instruments and Methods in Physics Research covers all aspects of the interaction of energetic beams with atoms, molecules and aggregate forms of matter. This includes ion beam analysis and ion beam modification of materials as well as basic data of importance for these studies. Topics of general interest include: atomic collisions in solids, particle channelling, all aspects of collision cascades, the modification of materials by energetic beams, ion implantation, irradiation - induced changes in materials, the physics and chemistry of beam interactions and the analysis of materials by all forms of energetic radiation. Modification by ion, laser and electron beams for the study of electronic materials, metals, ceramics, insulators, polymers and other important and new materials systems are included. Related studies, such as the application of ion beam analysis to biological, archaeological and geological samples as well as applications to solve problems in planetary science are also welcome. Energetic beams of interest include atomic and molecular ions, neutrons, positrons and muons, plasmas directed at surfaces, electron and photon beams, including laser treated surfaces and studies of solids by photon radiation from rotating anodes, synchrotrons, etc. In addition, the interaction between various forms of radiation and radiation-induced deposition processes are relevant.
