High Voltage Engineering Europa (HVE) has designed a vacuum-insulated tandem accelerator dedicated to radiocarbon (14C) analysis. A unique feature of the design is a magnetic charge state selector that is incorporated in the high voltage terminal, which reduces the primary source of background that originates from the injection of 13CH− to negligible levels. As a result, background levels in the low 10−16 regimes are anticipated, thus supporting the most stringent 14C dating applications. Another feature of the system is the incorporation of several slit feedback loops for stabilization of the position of the ion beam throughout the system, which avoids drift and ensures stable, long-term operation. Finally, this article presents measurements and quantitative analysis of background contributions from 13CH−.

一种新型专用 HVE 14C AMS 系统

High Voltage Engineering Europa (HVE) 设计了一种真空绝缘串联加速器，专门用于放射性碳（14三）分析。该设计的一个独特之处是在高压端子中集成了一个磁荷状态选择器，它减少了源自注入13甲烷-到可以忽略的水平。因此，背景水平在低 10-16制度是预期的，从而支持最严格的14C 约会应用程序。该系统的另一个特点是结合了多个狭缝反馈回路，用于稳定整个系统中离子束的位置，从而避免漂移并确保稳定、长期运行。最后，本文介绍了来自背景贡献的测量和定量分析13甲烷-.
