SNS Timing System: Ensuring Precision Timing for a Large-Scale Physics Facility

Title: SNS Timing System: Ensuring Precision Timing for a Large-Scale Physics Facility

Research Question: How can a timing system be designed to synchronize and distribute timing signals accurately and efficiently for a large-scale physics facility like the Spallation Neutron Source (SNS)?

Methodology: The researchers designed a timing system that would synchronize the operation of the SNS's LINAC, accumulator ring, and neutron choppers. They also aimed to distribute appropriate timing signals to various accelerator systems and facilities. The system would handle signals like the ring RF clock, real-time timing triggers, and machine mode events.

Results: The SNS Timing System was designed to meet stringent timing accuracy requirements. For neutron chopper synchronization, the system aimed for an accuracy of ±0.5 µs, while for the LINAC, it was required to synchronize injection about 896 µs before extraction. The system also had to cater to the needs of various beam diagnostics groups, requiring synchronization with the ring period and accurate timing to within ±5 ns.

Implications: The SNS Timing System is crucial for maintaining the performance and operation of the SNS. Its successful implementation ensures that the facility can synchronize and distribute timing signals accurately, enabling efficient operation of the accelerator and neutron choppers, and facilitating precise beam diagnostics. This contributes to the overall success of the SNS in conducting cutting-edge research in various fields of physics.
