Abstract

This paper presents the concept of an ultra-stable, thermally independent precision voltage divider tailored for direct current (DC) voltages up to 60 kV. Key features of this voltage divider include minimal voltage dependence, excellent stability, and resistance to external temperature variations. The innovative approach involves its fabrication using 3D printing technology, allowing easy replication by project partners. This precision voltage divider leverages commercially available precision resistors, drawing upon successful outcomes from the FutureEnergy 19ENG02 and HVDC ENG07 Projects.

In these experiments, which involve ion acceleration and laser probing of electronic transitions, voltage dividers are integrated into setups such as COALA (TU Darmstadt), BECOLA (Michigan State University), COLLAPS (CERN/ISOLDE), and ATLANTIS (Argonne National Laboratory). Monitoring the applied acceleration potential, these dividers allow one to consider and counteract long-term drifts and thereby improving measurement accuracy.

用于校准和实验的超稳定3d打印精密分压器

本文提出了一种超稳定、热无关的精密分压器的概念，该分压器专为直流电（DC）电压高达60 kV而设计。该分压器的主要特点包括最小的电压依赖性，优异的稳定性和对外部温度变化的抵抗力。创新的方法包括使用3D打印技术制造，允许项目合作伙伴轻松复制。这种精密分压器利用市售的精密电阻器，借鉴了FutureEnergy 19ENG02和HVDC ENG07项目的成功成果。在这些涉及离子加速和电子跃迁激光探测的实验中，分压器被集成到诸如COALA（达姆施塔特工业大学）、BECOLA（密歇根州立大学）、COLLAPS（欧洲核子研究中心/ISOLDE）和ATLANTIS（阿贡国家实验室）等装置中。监测应用的加速度势，这些分压器允许考虑和抵消长期漂移，从而提高测量精度。
