To develop a high-precision timing and protection system for the neutral beam injector to enhance safety and performance.
Designed a protection system using the JYTEK PXIe hardware platform and Linux RT for synchronization.
Implemented software-defined automatic arc detection and re-ignition logic for managing breakdown events.
Established a remote communication module based on the UDP protocol for automated control.
Achieved rapid fault response, with arc signal detection to output cut-off latency within microseconds.
Validated re-ignition logic stability across typical operating conditions: normal recovery, multiple retries, and emergency stop.
Ensured timing integrity and pulse width consistency during fault recovery.
