Description

The Linac of Taiwan Light Source (TLS) has operated for over thirty years, necessitating modernization to ensure sustainability operation. A new digital low-level RF (DLLRF) control system has been developed to replace aging components and address the situation of having only a single backup unit. The MTCA.4 platform was adopted for its scalability and high-performance throughput. The system integrates the DACs module for arbitrary waveform generation with external triggering, and a direct-sampling down-converter with the ADCs module for waveform acquisition and advanced real-time diagnostics. The DLLRF interface has been fully integrated into the EPICS framework for seamless compatibility with existing controls. The new system supports I/Q waveform downloads with online amplitude and phase adjustments, and it provides waveform digitization capabilities for monitoring RF signals associated with the klystron modulator. Dedicated graphical applications have been designed and integrated into the current operator interfaces. The MTCA.4-based DLLRF system has been successfully deployed and validated during routine operations. This paper presents the development, implementation, and operational results of the upgraded control system.
