Nanosecond-Range Multiple-Pulse Synchronization Controlled by Magnetic Switches Based on a Communal Magnetic Core

Initial experimental results of nanosecond-range multiple-pulse synchronization controlled by magnetic switches on a communal magnetic core were presented in detail in this paper. Magnetic switches on a communal core are designed, and different experiments for the multiple-pulse synchronization tests are also put forward. The central principle is that the communal magnetic core compels the multiple magnetic switches saturating at the same time. In the single driving circuit mode, a high-voltage capacitor was employed to discharge to two branches of loads and magnetic switches based on a communal magnetic core, and the average synchronization accuracy of the two magnetic switches was measured at 1.6 ns under 10 shots, with jitter at 0.6 ns. Synchronization accuracies of multiple magnetic switches were also compared under the cases of a communal core and separate cores. Two high-voltage cable lines with the same length were also used as pulse forming lines to discharge to two branches of load resistors and magnetic switches on a communal core, respectively. When a single driving circuit was used for charging, experimental results showed that the average synchronization accuracy of the two magnetic switches was about 2.7 ns under 10 shots, with jitter at about 3.3 ns. Potential applications of the communal-core synchronization technology are also put forward.
