Propagation Characteristics of Surge Generated due to Internal Arc Discharge in Superconducting Magnet

초전도 마그네트 시스템 내부 아크방전에 의한 발생 서어지의 전파특성

Transient voltage distribution tests are carried out to evaluate effects of a high frequency oscillating voltage generated in a superconducting magnet as a result of the arc discharge extinction. Especially, the effects of temperature and conduction state of the magnet conductor on surge behavior are carefully investigated. Based on the results of simulation tests, it is shown that internal voltage waveforms are influenced by its transmission along the superconducting wire and reflection at the terminal and that attenuation process of the waveforms depends considerably on the conductor resistance which decreases with lowering the temperature.
