A field programmable gate array-based timing and control system for the dynamic compression sector.

Area of Science:

• Materials Science
• Accelerator Physics
• Instrumentation

Background:

• The Dynamic Compression Sector (DCS) at the Advanced Photon Source (APS) requires precise synchronization for its laser shock station.
• Accurate timing is essential for coordinating x-ray choppers, shutters, laser triggers, and diagnostics with incoming x-ray pulses.

Purpose of the Study:

• To develop and evaluate a Field Programmable Gate Array (FPGA)-based timing and trigger control system for the DCS.
• To achieve low timing jitter synchronization for dynamic compression experiments.

Main Methods:

• Developed an FPGA system synchronized to the APS 352 MHz radio frequency clock.
• Integrated components including a Zynq FPGA, debug card, line drivers, and power supply.
• Implemented a user-friendly graphical interface for precise delay and offset adjustments.

Main Results:

• Achieved low timing jitter of 15.5 ps root mean square (rms) relative to the APS clock.
• The system is suitable for synchronizing with the 100 ps (FWHM) x-ray bunch duration.
• The FPGA system has been operational and continuously improved since commissioning.

Conclusions:

• The developed FPGA timing and trigger control system meets the stringent synchronization requirements for dynamic compression science at the APS.
• The system's low jitter and precise control enable advanced experimental capabilities.
• This instrumentation advances the field of dynamic compression research.
