A flexible system-on-a-chip control hardware for atomic, molecular, and optical physics experiments.

Area of Science:

• Atomic, Molecular, and Optical (AMO) Physics
• Experimental Physics Control Systems

Background:

• Traditional control systems for AMO physics experiments can be costly and complex.
• There is a need for flexible, high-speed, and precisely timed control solutions for modern experimental setups.

Purpose of the Study:

• To develop and implement a cost-effective control system core for AMO physics experiments.
• To leverage field-programmable gate array (FPGA) technology for high-performance experimental control.
• To enable precise synchronization of multiple control boards for distributed systems.

Main Methods:

• Implementation of a control system core on a commercial low-cost FPGA System-on-a-Chip (SoC) board running Linux.
• Utilizing Gigabit Ethernet for high-speed data transmission and remote system operation.
• Development of a novel auto-synchronization scheme for multi-board synchronous operation.

Main Results:

• Achieved contiguous output and input sampling rates up to 40 MHz.
• Demonstrated synchronous operation of multiple boards with timing errors approaching 1 nanosecond.
• Successfully controlled diverse signal types (digital, analog, radio frequency) with precise timing.

Conclusions:

• The implemented control system core provides a powerful and versatile solution for AMO physics experiments.
• The novel auto-synchronization scheme is suitable for complex distributed experimental setups requiring high timing precision.
• The use of low-cost FPGA boards offers a scalable and accessible platform for advanced experimental control.
