Description
Abstract
The pulsed-wire method (PWM) is employed for magnetic-field characterization of accelerator insertion devices. However, reflected transverse waves in PWM systems can introduce significant errors in the reconstructed magnetic-field distribution. These reflections arise because the conductor must be fixed at both ends, causing any traveling wave reaching a fixed boundary to generate a reflected component. In this study, we investigate the suppression of reflected waves using mechanically dampers integrated into the PWM setup. Experimental results demonstrate that the dampers attenuate wave reflections by more than 80%, substantially enhancing the accuracy, stability, and repeatability of the PWM measurement technique.
