自从我们第一次报告基尔加速器质谱仪(AMS)系统的性能和我们在样品制备方面的早期工作以来，我们已经建立了一些系统来提高实验室的样品质量和产量。还对辅助医疗管理系统进行了轻微修改，主要是为了减少维持系统处于最佳状态所需的工作量和时间。讨论了AMS系统的20端口还原系统、气动靶标压力机和远程报警单元的设计和性能，并概述了去年取得的成果和获得这些成果的程序。统计分析表明，在我们目前的水平(现代样品为0.3%)，AMS系统对测量不确定度的贡献可以忽略不计。
Since our first report on the performance of the Kiel accelerator mass spectrometry (AMS) system and our early work on sample preparation, systems have been built to improve the sample quality and throughput of the laboratory. Minor modifications were also made on the AMS system, mainly in order to reduce the amount of work and time needed to maintain the system in optimal condition. The design and performance of a 20-port reduction system, a pneumatic target press, and a remote alarm unit for the AMS system are discussed, along with an overview of the results obtained during the last year and the procedure used to obtain them. Statistical analysis shows that the contribution of the AMS system to the measuring uncertainty at our current level (0.3% for a modern sample) is negligible.
