“…The technique exhibits variations depending on the measurement target, characteristics of the incident signal, and measurement equipment. As a representative instance, time domain reflectometry (TDR) [24,25], frequency domain reflectometry (FDR) [26,27], time-frequency domain reflectometry [20,28], and spread spectrum TDR [29,30] have been developed. In this work, we utilize the TDR method using a vector network analyzer (VNA).…”

Impregnation plays a crucial role in the performance and protection of superconducting magnets. To investigate the impregnation status during quench training, a vector network analyzer (VNA)-based time domain reflectometry (TDR) is introduced. The proposed method and analyses focus on demonstrating their applicability within canted-cosine-theta (CCT) magnets, covering both artificially induced quenches using spot heaters and naturally occurring quenches. To verify the performance of the proposed method, VNA-based TDR is applied to CCT Subscale magnets developed in the US Magnet Development Program. The findings contribute to a deeper understanding of CCT superconducting magnet behavior and inform strategies for improving their performance.
