Description

We present progress on a feedback control system for real-time optimization of five transverse wigglers to generate a sawtooth phase-space correlation. A recently proposed transverse wiggler-based correlation control method requires simultaneous tuning of 5-10 wigglers, each with three control variables (phase, amplitude, and period), which makes the tuning challenging. An upcoming experiment to demonstrate bunching factor enhancement using a sawtooth correlation will implement five wigglers. For a successful demonstration, we are developing a closed-loop framework that will use single-shot, projection-based transverse phase-space diagnostics to iteratively update wiggler parameters. The system will support remote control and real-time adjustment during operation.
